 DESCRIPTION
      html-pretty filters its HTML or SGML input from stdin, or from one or
      more named files given on the command line, and prettyprints it to
      stdout, standardizing the spacing, and providing indentation to expose
      the document structure.

      When its input is just a plain text file in the ASCII or ISO 8859-1
      character sets, a major part of the conversion of text to
      grammatically-correct HTML can be done automatically, especially if
      the -convert-paragraph-breaks option is used.  Section headings,
      verbatim, and tabular material will, however, require manual editing.

      HTML (HyperText Markup Language) is the language used to specify
      formatting instructions in text files intended for viewing with
      World-Wide Web (WWW) client programs (browsers), such as amaya(1),
      arena(1), chimera(1), grail(1), hotjava(1), jde(1), lynx(1),
      netscape(1), panorama(1), and xmosaic(1).

      The WWW idea began in late 1992, and because viewer programs support
      display of text, line drawings, color raster images, hypertext links,
      and uniform access to several Internet services, including file
      transfer, in the first two years, the number of WWW servers grew from

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



      zero to several hundred thousand, and some of the more popular sites
      receive up to twenty-five million accesses a day from all over the
      Internet.  Consequently, many Internet computer users are beginning to
      write HTML documents for their own home pages, and html-pretty is
      written for them.

      The goal of a prettyprinter is to recognize all legal inputs, and
      produce output that is indented to reflect the structure, and in which
      line lengths have been restricted for improved readability.
      Irregularities in coding practice, and outright errors, are more
      likely to be detected in the prettyprinted output, than in the input.

      SGML (Standard General Markup Language, ISO 8879), and its particular
      document type definition instance, HTML, follow a rigorous grammar for
      text markup that makes it possible to clearly identify document parts,
      such as headings, sections, subsections, paragraphs, figures, tables,
      equations, and so on, and files with such standardized markup are
      particularly good candidates for prettyprinting.

      The definition of HTML is still evolving.  Version 2.0 (Fall 1994) is
      implemented by almost all browsers.  Version 3.0, informally called
      HTML Plus, was introduced in March, 1995, and the arena(1) browser was
      developed at the World-Wide Web Consortium, W3C, to serve as a testbed
      for it.

      Although Version 3.0 is a superset of version 2.0, it proved too
      difficult for browser implementors to incorporate support for it in a
      reasonable time, and it was withdrawn in Fall, 1996.  Version 3.2 was
      released on 14 January 1997, but despite its higher version number, it
      lacks many of the new features introduced in version 3.0, notably for
      mathematical markup, but importantly, it does include support for
      figures and tables.  As with version 3.0, there is also a testbed
      browser, this time called amaya(1), and augmented with the ability to
      edit HTML files, providing a (simple-minded) WYSIWYG editor interface
      that some users may find convenient for creating and maintaining HTML
      files.

      At the time of writing in Fall, 1997, only the amaya(1) and
      netscape(1) browsers appear to have implemented all, or most, of HTML
      3.2.

      Further information about HTML versions 3.0 and 3.2 can be found on
      the World-Wide Web at the Uniform Resource Locators (URLs)

      The next version of HTML, code-named Cougar, is under development, and
      will become version 4.0 when it is finally released.  The first draft
      public release was on 8 July 1997, and a second proposed
      recommendation followed on 7 November 1997.  For details, visit URLs

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997

      Interestingly, translations of the version 4.0 specification to at
      least 18 other human languages are in progress: see URLs

           http://www.w3.org/TR/WD-html40/translations.html
           http://www.w3.org/TR/PR-html40-971107/translations.html

      html-pretty recognizes all HTML tags in the grammars of versions 1.0,
      2.0, 3.0, 3.2, and proposed 4.0, plus a few vendor-specific
      extensions.

      One significant difference between the grammar versions is that the
      HTML tag <P> is a paragraph separator in version 2.0, while it is a
      paragraph begin in later versions, and consequently expects to have a
      matching </P> paragraph end tag that is not required in 2.0.  html-
      pretty will supply missing </P> tags, and delete empty <P> ... </P>
      environments.  Since HTML translators ignore unknown tags, this is
      transparent to HTML version 2.0 implementations, and causes no
      problems.

      html-pretty expects that its input is reasonably well-formed. Usually
      it is sufficient that the file can be displayed by one or more WWW
      browsers, producing the expected form.  However, it would be unwise to
      write a large amount of program code without a compiler to check it,
      and it is similarly unwise to write documentation in HTML or SGML
      without at least a validating parser to ensure that the text is
      syntactically correct.

      Fortunately, at least two such programs are publicly available (thanks
      to the generosity of their author, James Clark), nsgmls(1) and
      sgmls(1), together with UNIX shell scripts, html-check(1) and html-
      ncheck(1), to facilitate their use with HTML files.  In addition, the
      nsgmls(1) distribution is accompanied by two SGML tag normalizers,
      sgmlnorm(1) and spam(1), and there is a UNIX shell script, html-
      spam(1), for one of them.  You may therefore find it useful to apply
      html-spam(1), and either html-check(1) or html-ncheck(1), to your HTML
      files, and fix all of the errors that they detect, before filtering
      the files with html-pretty.

      HTML strictly requires a certain amount of boiler-plate to be wrapped
      around the text, and there is ample evidence that most HTML files omit
      these wrappers, because WWW browsers are written to be tolerant of
      grammatical deviations.  html-pretty will supply the wrappers if they
      are omitted; indeed, if given an empty input file, html-pretty
      produces output similar to this:

           <!-- -*-html-*- -->
           <!-- Prettyprinted by html-pretty flex version 1.00 [11-Nov-1997] -->

           <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">

           <HTML>
               <HEAD>
                   <TITLE>
                       <!-- Please supply a descriptive title here -->

               </BODY>
           </HTML>

      This example, minus the comments <!-- ... -->, shows the minimal
      markup that should be expected in an HTML file, although the grammar
      permits the HTML, HEAD and BODY environments to be implicitly assumed
      if they are omitted.  While most WWW browsers ignore the DOCTYPE
      declaration, it is essential for SGML parsers, since it identifies the
      grammar rules that apply to what follows.  Two recent WWW browsers,
      amaya(1) and panorama(1), are SGML-grammar based, and may require a
      valid DOCTYPE declaration.

 OPTIONS
      Command-line options affect all following filenames.  Option values
      are always provided as separate arguments following the option name.
      Letter case in option names is not significant, although it may be in
      option values.  Option names may be abbreviated to any unique leading
      prefix, unless a shorter prefix is documented.

      Any argument that begins with a hyphen is expected to be an option,
      and will raise an error if it is not recognized.  If a filename begins
      with a hyphen, you therefore need to disguise it by supplying a
      leading directory path.  For example, ./-foo represents the file named
      -foo in the current directory in UNIX.

      GNU- and POSIX-style options of the form --name are also recognized:
      they begin with two option prefix characters.

      For every option -xxx that sets a Boolean flag to be acted upon later,
      there is a corresponding -no-xxx option to override it.  The negative
      forms are normally not required, but are necessary to counteract
      options set in a style file.

      -author          Show author information on stderr and quit after
                       processing any remaining command-line options that
                       precede the next command-line HTML file.

      -blank-line-warning
                       Unlike most word processing and typesetting systems,
                       and ordinary typewritten text, in HTML and SGML,
                       blank lines do not imply a paragraph break, except in
                       verbatim environments.  You can select this option to
                       get warnings about such blank lines.  They will be
                       reduced to a single blank line, leaving space for
                       later manual insertion of a <P> tag, if that was
                       indeed what was intended [default: -no-blank-line-
                       warning].

                       If you specify the -convert-paragraph-breaks option,
                       then this option will have no effect.

      -brief           Brief mode: exclude the standard boiler-plate wrapper
                       of !DOCTYPE, HTML, HEAD, and BODY tags [default:
                       -no-brief].

                       This option, in conjunction with -no-comment-banner,
                       is convenient for prettyprinting small fragments of
                       text, such as from inside a text editor.  It can also
                       be used for portions of larger documents (e.g.,
                       chapters of a book) that are not in themselves
                       complete HTML files.

                       This option can be abbreviated to -b.

      -catalogfile filename
                       Specify an alternate catalog file to override the
                       default one.  See the CATALOG DIRECTORY section for
                       more details.

                       This option can be abbreviated to -c.

      -check-tag-nesting
                       Use built-in tables, or tables from style files, of
                       tag-is-contained-in and tag-cannot-contain relations
                       to check that tags are properly nested.  The rules
                       that govern this are very complex, and depend on the
                       grammar level chosen. The precise relations are
                       tabulated in the HTML GRAMMAR CONSTRAINTS section,
                       and the way they are provided to html-pretty is
                       described in the STYLE FILES section.

                       Because this option can lead to a large number of
                       warning messages when optional end tags are omitted,
                       the default is -no-check-tag-nesting.

                       Nevertheless, when a proper SGML parser, such as
                       html-check(1) or html-ncheck(1), is not available,
                       this option can be very helpful in diagnosing errors

      -comment-banner  Generate a leading comment banner containing the
                       prettyprinter version number and date, the current
                       date and time, and the personal name and email
                       address of the user who ran the prettyprinter
                       [default: -comment-banner].

      -convert-paragraph-breaks
                       Convert paragraph breaks (sequences of one or more
                       blank or empty lines) to HTML <P> tags [default:
                       -no-convert-paragraph-breaks].

                       This option is intended for converting text files to
                       HTML; it should not be used when the input file is
                       already HTML, unless the intent really is to insert
                       explicit paragraph tags.

                       This option has no effect on blank lines inside
                       verbatim environments.

      -copyright

      -copyleft        Show copyright information on stderr and quit after
                       processing any remaining command-line options that
                       precede the next command-line HTML file.

      -email-address user@hostname
                       Supply an alternate electronic mail address to be
                       used in the comment banner and the LINK tag.
                       Otherwise, a default address is constructed from the
                       current user name and host name, when that
                       information is available from the operating system.

                       This option may also be spelled -e-mail-address,
                       since both e-mail and email are about equally common
                       abbreviations on the World-Wide Web.

      -extend-style 'style: TAG TAG ...'

      -extend-style 'TAG: TAG TAG ...'
                       These options, whose name can be abbreviated to just
                       -e, provide a quick command-line alternative to the
                       style file feature of the -stylefile option.  They
                       permit you to augment the list of tags associated
                       with a particular formatting style class, or to add a
                       list of tags to the same class as an existing tag (to
                       avoid the need to know the style class names), but
                       only for the duration of the current process.

                              04 December 1997



                       Since a tag can belong to only a single style class
                       at one time, specification of existing tags with
                       these options effectively removes their old style
                       class association.

                       html-pretty distinguishes between the two cases by
                       looking up the first name in its tag table.  If it is
                       entirely in uppercase, then it might be found there.
                       Otherwise, it is a style class name.

                       If the style class is not recognized, an error
                       message is issued with a list of the recognized class
                       names, and execution is terminated after processing
                       any remaining command-line options that precede the
                       next command-line HTML file.  Thus, an option
                       -extend-style foo:bar' or -extend-style help=me' with
                       obviously incorrect class and tag names can be used
                       to coax a list of the valid ones from html-pretty; it
                       will respond with something like this:


                            :1:unknown style [foo] command [BAR] at line 0
                            in style source [command-line]

                            The recognized style classes are:
                                    body doctype font head html
                                    line-break link list list-header
                                    list-item markup-declaration math

                                    standalone-nocheck title verbatim

                       The output line width in this list is governed by the
                       -width option.

                       You can assign tags to the special style class name
                       default to make them unknown (and also, warned about,
                       if you supply the -unknown-tag-warning option), e.g.,
                       default:blink.

                       Because some operating systems do not allow embedded
                       spaces in command-line arguments, you can separate
                       the tags in the value string with a comma instead of
                       whitespace.  Also, you can use an equals sign instead
                       of a colon after the first word.  For example, the
                       value strings


                            font:A,MEDIUM
                            font=A,MEDIUM
                            'font   =   A    MEDIUM'

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



                            'font :     A,,,,MEDIUM'

                       all assign tags A and MEDIUM to the font style class.
                       Incidentally, some people prefer A (anchor) tag pairs
                       to be treated this way, rather than their default of
                       being placed on separate lines, even though long
                       hypertext references in <A HREF="..."> make this
                       style hard to read.

                       For more information on this topic, see the STYLE
                       FILES section below.

      -file filename   Supply an alternate input filename for use in the
                       output comment banner.  This overrides the actual
                       filename(s), and provides a way to name the output,
                       even when no named input file is available, because
                       standard input is redirected, or comes from a pipe.

      -grammar-level grammar
                       Select a grammar level that in turn will select a
                       suitable style file.  See the CATALOG DIRECTORY and
                       STYLE FILES sections for more details.

                       Lettercase is not significant in grammar-level names.

                       You can use this option, together with the -unknown-
                       tag-warning option, to help detect use of HTML tags
                       that are not part of the grammar.  However, a better,
                       and grammatically rigorous, way to do this is to use
                       a validating SGML parser, such as those accessible
                       via the html-check(1) and html-ncheck(1) scripts.

                       The built-in default grammar level is a union of the
                       HTML grammar levels 1.0, 2.0, 3.0, 3.2, and proposed
                       4.0, plus selected browser-vendor extensions.

                       A properly-installed html-pretty always supports at
                       least grammar levels 1.0, 2.0, 3.0, 3.2, 4.0, plus
                       one named all which contains a union of all of the
                       grammar styles in the catalog directory.  This will
                       be similar to the built-in default style, but may
                       differ from it in minor details, since it is easier
                       to augment the style file than it is to rebuild and
                       reinstall the software.

                       There is also a `grammar level' named dtd; it
                       augments the normal style rules with additional ones
                       for extra declarations and tags found in SGML and
                       HTML Document Type Definition (DTD) files.

                              04 December 1997



                       If you specify an incorrect grammar level, html-
                       pretty will display a message showing the available
                       levels, and then quit:


                            html-pretty -g foo
                            :1:could not find grammar level [foo] in
                            catalog file [/usr/local/share/lib/html-pretty/catalog]:
                                levels available:  all dtd 2 2.0 3 3.0 3.2 4 4.0

                       If the style file has a public style class entry, the
                       output DOCTYPE declaration will use its value,
                       instead of a built-in default; see the STYLE FILES
                       section below for details.

                       Tip: if you want to find out the differences in the
                       sets of HTML tags accepted by two different grammar
                       versions, use this option with the -print-stylefile
                       and -width options like this:


                            html-pretty -w 0 -g 3.2 -p >foo.3.2
                            html-pretty -w 0 -g 4.0 -p >foo.4.0
                            diff foo.3.2 foo.4.0

                       The difference listing will show just those style
                       classes where the tag lists differ, since each class
                       will be complete on one (possibly long) line.

      -help or -?      Display brief usage information on stderr and quit
                       after processing any remaining command-line options
                       that precede the next command-line HTML file.

      -indent nnn      Set the number of spaces for each indentation level
                       [default: 4].

      -keep-format     Treat the input stream as verbatim text whose visual
                       format is to be exactly preserved.  It will be
                       converted to the body of a preformatted HTML
                       environment, <PRE> ... </PRE>, and all characters
                       will be output unchanged, except for the four
                       characters `<', `>', `&', and `"', which will be
                       translated to SGML entities `&lt;', `&gt;', `&amp;',
                       and either `&quot;' or `&34;' (depending on the
                       grammar level), respectively.

                       This option is useful for converting non-HTML text to
                       HTML when the linebreaking and indentation are
                       already decided, such as preformatted tables, samples
                       of computer program input and output, and programming
                       language fragments.

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



                       Horizontal tab characters are treated like spaces in
                       HTML, but most Web browsers will display text
                       containing tabs as if each tab caused blank fill up
                       to, and including, the next column which is a
                       multiple of eight, which is the conventional behavior
                       on many systems. The visual appearance is correct if
                       the text is displayed with a fixed-width font, but is
                       usually wrong with a proportionally-spaced font.

                       However, when asked to save the file as plain text,
                       some browsers will save text with tabs, and others
                       will save text with tabs expanded to spaces, thereby
                       preserving the original appearance.  When the same
                       text is cut with the mouse and pasted into another
                       window, some browsers preserve tabs, and others
                       convert it to spaces.  And even more confusingly, a
                       browser that converts tabs to spaces in a saved file
                       may leave tabs intact in cut-and-pasted text!

                       In most cases, tabs are not significant, but they are
                       for UNIX Makefiles, so if your text has significant
                       tabs, you should incorporate a warning that they will
                       likely be destroyed by the Web browser, and will need
                       to be restored manually, or with a pass through a
                       filter such as unexpand(1).

                       html-pretty always treats tabs as ordinary
                       characters, but if you want to be sure of correct
                       display of tabs according to the conventional blank-
                       fill rule, you should filter the input to html-pretty
                       using a tab expander such as expand(1).

                       For Fortran code containing tab characters, the
                       meaning of tabs is context sensitive, and you need to
                       use a Fortran-tab aware converter.  There is no
                       standard UNIX utility to do this, although a local
                       emacs(1) editor function M-x detab-fortran will do
                       the job.

      -logfile filename
                       Redirect warning and error messages from stderr to
                       the indicated filename.  This option is provided for
                       user convenience on poorly-designed operating systems
                       (e.g., IBM PC DOS) that fail to provide for
                       redirection of stderr to a specified file.

                       This option can also be used for discarding messages,
                       with, e.g., on UNIX systems, -logfile /dev/null.

                       If the file cannot be opened for output, html-pretty
                       will terminate silently with a non-zero exit code,

                              04 December 1997



                       because the internal attempted redirection required
                       the closure of stderr, making it unavailable for
                       printing further error messages.

      -no-blank-line-warning
                       Override an earlier -blank-line-warning option.
                       Unlike most word processing and typesetting systems,
                       and ordinary typewritten text, in HTML and SGML,
                       blank lines do not imply a paragraph break, except in
                       verbatim environments.  html-pretty will therefore
                       normally silently reduce such blank lines to a single
                       space [default: -no-blank-line-warning].

                       If you specify the -convert-paragraph-breaks option,
                       then this option will have no effect.

      -no-brief        Override an earlier -brief option, so that the
                       standard wrapper !DOCTYPE, HTML, HEAD, and BODY tags
                       are generated  [default: -no-brief].

      -no-check-tag-nesting
                       Suppress checks for correct tag nesting [default:
                       -no-check-tag-nesting].

      -no-comment-banner
                       Suppress generation of the default leading comment
                       banner.

                       This option can be abbreviated to -n, since it may be
                       used frequently [default: -comment-banner].

      -no-convert-paragraph-breaks
                       Do not convert paragraph breaks (sequences of one or
                       more blank or empty lines) to HTML <P> tags [default:
                       -no-convert-paragraph-breaks].  Instead, unless the
                       -blank-line-warning option has been given, the empty
                       lines will be reduced to a single space.

      -no-keep-format  Override an earlier -keep-format option, and thus
                       permit reformatting of the input stream [default:
                       -no-keep-format ].

      -no-print-stylefile
                       Override an earlier -print-stylefile option, and
                       therefore, do not terminate execution before
                       processing style files [default: -no-print-
                       stylefile].

      -no-quiet        Override an earlier -quiet option, to restore output
                       of warning messages on stderr [default: -no-quiet].

      -no-read-stylefiles
                       Suppress reading of the three default style files
                       (see the STYLE FILES section below) [default: -read-

                       Style files implicitly specified with -grammar-level
                       options, or explicitly specified with -stylefile
                       options, will still be processed.

      -no-trace-opens  Override an earlier -trace-opens option, so that file
                       opening attempts are not traced on stderr [default:
                       -no-trace-opens].

      -no-unknown-tag-warning
                       Override an earlier -unknown-tag-warning option, so
                       that unknown HTML tags will not elicit a warning
                       message [default: -no-unknown-tag-warning].

      -no-warnings-in-comments
                       Override an earlier -warnings-in-comments option, so
                       that warning and error messages are written only to
                       stderr (which might have been redirected with the
                       -logfile option) [default: -no-warnings-in-comments].

      -outfile filename
                       Redirect output from stdout to the indicated
                       filename.  This option is provided for user
                       convenience on operating systems that fail to provide
                       for redirection of stdout to a specified file.

      -personal-name name
                       Supply an alternate personal name string to be used
                       in the comment banner.  Normally, the personal name
                       is determined via the current user name, when that
                       information is available from the operating system.

      -print-stylefile Print a style file on stdout and quit after
                       processing any remaining command-line options that
                       precede the next command-line HTML file.

                       This option can be abbreviated to -p.

                       The output line width in the style file is governed
                       by the -width option described later.

                       already have been processed, and their changes will
                       be reflected in the output produced by this option.

                       Use this option to find out how each recognized tag
                       is processed, and also to get a template style file
                       that you can customize.  The style class names and
                       tag lists are ordered alphabetically for improved
                       readability.  For more details, see the STYLE FILES
                       section below.

      -quiet           Suppress output of warning messages on stderr.  Error
                       messages will, however, not be suppressed.

                       If you really want to discard error messages too,
                       then use the -logfile /dev/null option instead.

      -read-stylefiles Override an earlier -no-read-stylefiles option, so
                       that the three standard style files (see the STYLE
                       FILES section below) are read [default: -read-
                       stylefiles].

      -stylefile filename
                       Name a style file (see the STYLE FILES section below)
                       to augment html-pretty's built-in knowledge of HTML
                       tags.  This option may be given more than once, if
                       multiple initialization files are needed.

      -trace-opens     Trace all file-opening attempts, with a one-line
                       message on stderr for each [default: -no-trace-
                       opens].

                       This option can be helpful in analyzing file access
                       failures, and in uncovering the location of default
                       style files and the catalog directory.

      -unknown-tag-warning
                       Unknown HTML tags are always treated as ordinary
                       text, but with this option, you can request that a
                       warning be raised for each of them [default: -no-
                       unknown-tag-warning].

                       While this option is not a substitute for a
                       validating HTML parser, such as html-check(1) or
                       html-ncheck(1), it does provide a simple way to catch
                       use of non-standard tags.  See the -extend-style
                       option for a way to catch specific tags.

      -version         Show version information on stderr and quit after
                       processing any remaining command-line options that
                       precede the next command-line HTML file.

      -warnings-in-comments
                       Write warning and error messages as easily-
                       identifiable single-line HTML comments on stdout

                       [default: -no-warnings-in-comments].  This may
                       facilitate correction of problems in the output file,
                       since the messages can be located by context, rather
                       than by line number in the input file.

                       Messages are always written to stderr as well (which
                       might have been redirected with the -logfile option,
                       or suppressed with the -quiet option).

      -width nnn       Set the maximum output line width [default: 72].
                       This limit may be exceeded if an excessively long
                       string without embedded spaces is encountered, and it
                       is ignored completely inside preformatted or verbatim
                       text.

                       If you set the line width to 0, it will be treated as
                       `infinite' (i.e., the largest representable integer).
                       If you set it to a very small value, e.g., 1, then
                       the output will have one word per line, which might
                       actually be useful on occasion!

                       This option can be abbreviated to -w.

 FORMATTING CONVENTIONS
      html-pretty groups HTML tags into collections of style classes.  Tags
      within a single style class receive similar formatting.  The built-in
      style-class tag-membership lists recognize a large collection of tags
      from multiple grammar levels, and multiple browser vendor extensions,
      but all of the built-in lists can be modified by the user, as
      described in the -extend-style and -stylefile options above, and the
      STYLE FILES section below.

      The subsections which follow catalog the origins of the recognized
      tags, and then describe the available style classes in alphabetical
      order, listing their default tag members, and briefly sketching how
      the tags are formatted.

      Tags that are not explicitly named in these subsections, or in style
      files that are read at run time, are treated as normal text, and have
      no effect on the indentation or line breaking, other than their
      contribution toward the line length limit.

      Tags in the style classes doctype, line-break, math, plaintext, short,
      standalone, and standalone-nocheck make up the set of HTML tags with
      SGML content EMPTY, which means that end tags for them are forbidden.
      html-pretty will issue warnings about such end tags, but will leave
      their deletion to a human.

    Recognized HTML Tags
      HTML 2.0 contains the following 49 tags: A, ADDRESS, B, BASE,
      BLOCKQUOTE, BODY, BR, CITE, CODE, DD, DIR, DL, DT, EM, FORM, H1, H2,

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



      H3, H4, H5, H6, HEAD, HR, HTML, I, IMG, INPUT, ISINDEX, KBD, LI, LINK,
      LISTING, MENU, META, NEXTID, OL, OPTION, P, PLAINTEXT, PRE, SAMP,
      SELECT, STRONG, TEXTAREA, TITLE, TT, UL, VAR, and XMP.

      HTML 3.0 augments the 2.0 grammar with 53 additional tags: ABBREV,
      ABOVE, ACRONYM, ARRAY, ATOP, AU, BAR, BELOW, BIG, BOX, BQ, BT,
      CAPTION, CHOOSE, CREDIT, DDOT, DEL, DFN, DIV, DOT, FIG, HAT, INS,
      ITEM, LANG, LEFT, LH, MATH, NOTE, OF, OVER, OVERLAY, PERSON, PRE, Q,
      RIGHT, ROOT, ROW, S, SMALL, SQRT, STYLE, SUB, SUP, T, TAB, TABLE, TD,
      TH, TILDE, TR, U, and VEC.

      These tags are identified by their occurrence in the html.dtd and
      html-3.dtd document type definition files in lines like these:

           <!ENTITY % font " TT | B | I ">
           <!ENTITY % phrase "EM | STRONG | CODE | SAMP | KBD | VAR | CITE ">
           <!ELEMENT (%font;|%phrase) - - (%text)+>
           <!ELEMENT XMP - -  %literal>

      ENTITY declarations define text string substitutions, and ELEMENT
      declarations define the tags recognized by the grammar.

      HTML 3.2 introduced these 21 new tags: APPLET, AREA, BASEFONT, BIG,
      CAPTION, CENTER, DFN, DIV, FILE, FONT, MAP, NUMBER, PARAM, SCRIPT,
      SMALL, STRIKE, STYLE, SUB, SUP, TABLE, and U.

      Proposed HTML 4.0 introduces these 15 new tags: BDO, BUTTON, COL,
      COLGROUP, FIELDSET, FRAMESET, IFRAME, LABEL, NOFRAMES, NOSCRIPT,
      OBJECT, SPAN, TBODY, TFOOT, and THEAD.

    HTML Tag Omission
      The HTML grammar permits certain end tags to be omitted, when their
      implied position can be determined from the grammatical context.  In
      HTML 3.0, this includes the following tags: DD, DT, ITEM, LH, LI, OF,
      OPTION, P, ROW, STYLE, and TR.

      The HTML 3.2 grammar permits these end tags to be omitted: DD, DT,
      INPUT, LI, OPTION, and P.

      The HTML proposed 4.0 grammars permit these end tags to be omitted:
      COLGROUP, DD, DT, LI, OPTION, P, PARAM, TFOOT, THEAD, and TR.

      In all grammar versions, these tags never have end tags: AREA, BASE,
      BR, FRAME, HR, IMG, INPUT, ISINDEX, LINK, META, NEXTID, PARAM, and
      PLAINTEXT.

      In version 3.0, BASEFONT takes an optional end tag, but in succeeding
      versions, it must not have an end tag.

      In version 3.0, STYLE takes an optional end tag, but in succeeding
      versions, it must have an end tag.

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



      Supporting the tag-omission feature requires the ability to parse a
      complete SGML grammar, which requires a great deal more code than
      html-pretty provides.  Consequently, html-pretty does not support
      optional end tags; based on typical usage, they are expected to be
      always present, or always absent, according to the rules given below.
      Omitted end tags can be automatically supplied by an SGML tag
      normalizer, such as sgmlnorm(1), spam(1), or html-spam(1).

      html-pretty will warn about end tags that should not be present, based
      on the tags' membership in those style classes that are known not to
      have end tags.  However, it will not delete them from the output
      stream, because human judgment may be called for.  See the HTML
      GRAMMAR CONSTRAINTS section below for further details.

    Style Class: body
      The following HTML tag name must occur only once, with a begin/end
      pair, often with substantial amounts of intervening text: BODY.  The
      begin/end tags are prettyprinted on separate lines, with their
      enclosed text indented one level.  However, the BODY environment must
      occur after the HEAD environment, and one level inside the HTML
      environment.  html-pretty will supply this environment if needed,
      unless the -brief option has suppressed it.

    Style Class: comment
      Short HTML comments are output inline, like normal text.  Long ones,
      and ones with embedded angle brackets, are prettyprinted on separate
      lines.  Their internal form is preserved exactly, without any line
      wrapping, since they will often contain specially-formatted material.
      Any whitespace between the final "--" and the closing angle bracket
      will be eliminated, when possible.

    Style Class: doctype
      The following HTML tag name occurs only once, and should normally be
      the first non-comment tag in a file: !DOCTYPE.  html-pretty will
      supply this tag if needed, unless the -brief option has suppressed it.
      Strictly, this is not a tag, but rather a markup declaration, but
      html-pretty treats it as a special tag, and outputs it verbatim while
      checking for proper embedded comment balance.  For more details, see
      the COMMENTS IN HTML AND SGML section below.

    Style Class: font
      These HTML tag names occur in begin/end pairs, usually with smaller
      amounts of enclosed material.  They appear inline in the running text,
      and do not alter indentation: ACRONYM, B, BIG, BLINK, BT, CODE, DFN,
      EM, I, KBD, Q, REV, S, SAMP, SMALL, STRIKE, STRONG, T, TT, U, and VAR.

    Style Class: head
      This HTML tag occurs in begin/end pairs, which are prettyprinted on
      separate lines with enclosing text indented one level: HEAD.  However,
      this tag pair must occur only once in a file, and then only inside an
      HTML environment, and before the BODY environment.  html-pretty will

      supply this environment if needed, unless the -brief option has
      suppressed it.

    Style Class: html
      This HTML tag occurs in begin/end pairs, which are prettyprinted on
      separate lines with enclosing text indented one level: HTML.  However,
      this tag pair must occur only once in a file, and then only at the
      outermost level.  html-pretty will supply this environment if needed,
      unless the -brief option has suppressed it.

    Style Class: inline
      Tags in this class are treated as ordinary text, with no additional
      spacing requirements, or checks for enclosing environments.

      Neither the default built-in style, nor any of the standard grammar-
      level-specific style files, use this class.  It is provided to permit
      transparent handling of tags that may be added in future versions of
      the HTML grammars.

      There is a difference in the handling of a member of this class,
      compared to that for a tag which is not defined in any class.  The
      latter may result in warnings if the -unknown-tag-warning option has
      been selected, is allowed only in the BODY environment, and may cause
      a paragraph to end.  A tag in the inline style class may occur in
      either the HEAD or BODY environments, never raises unknown-tag
      warnings, and does not end a paragraph.

    Style Class: line-break
      This HTML tag marks an explicit line break, and has no matching end
      tag; preceding space is deleted, and a newline follows: BR.

    Style Class: link
      This HTML tag has no matching end tag; it appears alone on a separate
      line: LINK.  There is normally at least one LINK tag, in the HEAD
      environment, and html-pretty will supply one automatically if none is
      present in the input stream.

    Style Class: list
      These HTML tags names occur in begin/end pairs, and delimit lists.
      They appear on separate lines, with their enclosed text indented two
      levels: DIR, DL, MENU, OL, and UL.

    Style Class: list-header
      This HTML tag marks the title of a list: LH.  The begin/end tags are
      output on separate lines, indented one level from the enclosing list.

    Style Class: list-item
      These HTML tags mark the beginning of list items, and have matching
      end tags which are supplied if they are absent.  They are output on
      separate lines, indented one level from the enclosing list: DD, DT,
      and LI.

    Style Class: markup-declaration
      The following SGML markup declarations are also treated like special
      tags, and output verbatim while checking for proper embedded comment
      balance: !ATTLIST, !ELEMENT, !ENTITY, !NOTATION, !SGML, !SHORTREF, and
      !USEMAP.  However, html-pretty does no further checking about where
      these `tags' are legal.  Generally, they do not occur in HTML files,
      but are found mainly in DTD files.

    Style Class: math
      These HTML tag names occur only inside a MATH environment, and appear
      inline, without end tags, and without affecting indentation: ATOP,
      CHOOSE, LEFT, OF, OVER, RIGHT, and TAB.

    Style Class: math-pair
      These HTML tag names occur only inside a MATH environment, with
      begin/end pairs, and appear inline, without affecting indentation:
      ABOVE, BAR, BELOW, BOX, DDOT, DOT, HAT, ROOT, ROW, SQRT, SUB, SUP,
      TILDE, and VEC.

    Style Class: pair
      The following HTML tag names occur in begin/end pairs
      (<TAG>and</TAG>), often with substantial amounts of intervening text:
      A, ABBREV, ABSTRACT, ADDED, ADDRESS, APPLET, ARG, AROW, ARRAY, AU,
      BDO, BLOCKQUOTE, BQ, BUTTON, CAPTION, CENTER, CITE, CMD, COLGROUP,
      CREDIT, DEL, DIV, DIV1, DIV2, DIV3, DIV4, DIV5, DIV6, FIELDSET, FIG,

      MAP, MARGIN, MATH, MESSAGE, NOFRAMES, NOSCRIPT, NOTE, OBJECT, OPTION,
      PERSON, QUOTE, REMOVED, SELECT, SPAN, STYLE, TABLE, TBODY, TD,
      TEXTAREA, TFOOT, TH, THEAD, and TR.  They are prettyprinted on
      separate lines, with their enclosed text indented one level.

    Style Class: paragraph
      This HTML tag occurs in begin/end pairs, which are prettyprinted on
      separate lines with enclosing text indented one level: P.  However,
      paragraphing is tracked, empty paragraphs are discarded, and when new
      tags are encountered which are known to be illegal inside a paragraph,
      any open paragraph is automatically closed.  Thus, old-style HTML
      files with omitted </P> tags will usually get them added.  Unlike most
      word processors and many typesetting systems, blank lines in the SGML
      and HTML input stream do not imply a paragraph break; only the <P> tag
      does.

    Style Class: plaintext
      The HTML tag PLAINTEXT marks the beginning of verbatim text that
      continues to end-of-file; it appears on a separate line.  Although
      some HTML viewers will terminate the plaintext environment on reaching
      a matching end tag, </PLAINTEXT>, that practice is now considered
      erroneous.

      html-pretty will warn about this abberant environment, and recommend
      using <PRE> ... </PRE> instead.

    Style Class: section
      These HTML tags occur in begin/end pairs, which are prettyprinted on
      separate lines with enclosing text indented one level: H1, H2, H3, H4,
      H5, and H6.  However, they must be logically ordered: H1 before H2 ...
      before H6, with no intermediate header levels omitted, and they must
      appear at the first level inside the BODY environment.

    Style Class: short
      This HTML tag has no matching end tag; it appears alone on a separate
      line: ITEM.  However, tags in this class can be used only inside a
      BODY environment, and consequently, html-pretty will automatically end
      any open HEAD environment, and start a BODY environment, if needed.

    Style Class: standalone
      These HTML tags have no matching end tag; they appear alone on
      separate lines: CHANGED, HR, IMG, INPUT, RENDER, STYLES, and WBR.
      However, they may appear only inside the BODY environment, and outside
      a paragraph, and consequently, html-pretty will automatically end any
      open HEAD and P environments, and start a BODY environment, if needed.

    Style Class: standalone-nocheck
      These HTML tags have no matching end tag; they may appear in either
      the HEAD or the BODY environment, and they appear alone on separate
      lines: BASE, ISINDEX, META, and NEXTID.

      As the class name implies, they are not checked against rules that
      might restrict their placement with respect to other environments.

    Style Class: title
      This HTML tag occurs in begin/end pairs, which are prettyprinted on
      separate lines with enclosing text indented one level: TITLE.
      However, this tag pair is restricted to occurring only in the HEAD
      environment, and should normally only be given once.  html-pretty will
      supply this environment if needed, unless the -brief option has
      suppressed it, and will warn about multiple occurrences.

    Style Class: verbatim
      These HTML tags appear in begin/end pairs, delimit preformatted, or
      verbatim, text, and may occur only in the BODY environment: LISTING,
      NOBR, PRE, and XMP.  The beginning and ending tags are output on
      separate lines, with no indentation, and with the enclosed material
      copied exactly as it appeared in the input stream.

    Style Class: verbatim-nocheck
      These HTML tags appear in begin/end pairs, delimit preformatted, or
      verbatim, text, and may occur in either HEAD or BODY environments:
      SCRIPT and STYLE.  The beginning and ending tags are output on

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



      The SCRIPT and STYLE environments are not strictly verbatim
      environments, but since they contain material in one of several
      different scripting (Java, JavaScript, Tcl, VBScript, ...) or style-
      sheet (CSS, ...) languages, there is no reasonable way for html-pretty
      to reformat their contents, so they are included in this style class
      to prevent such reformatting.

 STYLE FILES
      In order to allow the user to control the formatting of particular
      HTML tags, html-pretty supports a powerful style file mechanism.  At
      startup, it processes a style file in the directory where the
      executable program was found, a second style file in the user's home
      directory, and a third style file in the current directory.  None of
      these need exist.  Next, during command-line argument processing,
      additional style files can be provided with the -stylefile option.
      These style files support system-specific, user-specific, directory-
      specific, and job- or file-specific prettyprinting control.

      The default name of the first three style files is system dependent:
      .html-prettyrc (UNIX), htmlpty.ini (IBM PC DOS), and html-pretty.ini
      (DEC VMS and OpenVMS).  The exact names depend on the name of the
      executable program, which is used to construct the style file names.
      If you renamed it to sgmlpretty.exe, the names would be .sgmlprettyrc
      on UNIX, and sgmlpretty.ini on other systems.

      More precisely, the program name passed to the prettyprinter as its
      zeroth argument is filtered by discarding any trailing version number
      and extension, then keeping the last consecutive string of characters
      that are letters, digits, hyphens, or underscores.  If the zeroth
      argument is empty, implying that the program name is unknown, then the
      name htmlpty is used; it is short enough to be acceptable to any
      reasonable file system.

      Automatic association of the style file names with the program name
      makes it easy to support multiple versions, e.g., html-pretty-2-0,
      html-pretty-3-0, html-pretty-3-2, and html-pretty-4-0 could select
      different HTML grammar versions, and on UNIX, and a few other
      operating systems, those programs could all be links to the same
      physical file, avoiding wasteful duplication of disk space.

      In the current implementation of html-pretty, all of the standard HTML
      tags defined in HTML grammar levels up to the proposed 4.0, plus a few
      browser vendor extensions, are hard-coded into the program as members
      of over twenty formatting-style classes, so that no external style
      files need exist for the program to run.  However, the -extend-style,
      -grammar-level, and -stylefile options allow the built-in rules to be
      completely replaced, if desired.

      The -print-stylefile command displays the built-in style rules as a
      set of style class names, each followed by a colon and a list of HTML
      tags in that style class.  Its output may be used without further

      There will be additional data at the end of this output, in the form
      of the tag relationships discussed below, but we omit it here because
      of its length.

      Notice that long lines can be continued on multiple physical lines,
      for improved readability, by terminating them with a backslash
      immediately before the newline.  The output line width in this file is
      governed by the -width option.

      As with the command-line -extend-style option, you can replace the
      colon with an equal sign, and the spaces between tags with commas, if
      you prefer.

      In addition to the style classes listed above, the special style class
      default can be used to force an HTML tag to revert to the default rule
      for unknown tags: just treat it as ordinary text, although if the
      -unknown-tag-warning option was specified, a warning will be issued
      for this now unknown tag.  You can use this to override earlier style

      file settings, and most of the built-in ones.

      The special style class public is associated with the SGML DOCTYPE
      identifier string, rather than with a list of HTML tags.  That string
      determines which grammar file is to be used for the document, and the
      value above corresponds to the most generic grammar level (2.0)
      recognized by almost all browsers, even though the style file includes
      tags from higher grammar levels.  The public style class is the only
      class whose value is a quoted string.

      If the tag list to the right of the colon (or equals sign) is empty,
      then all existing tags for that class are forgotten.  If an empty tag
      list is used with the default style class, then all tags for all
      classes are forgotten.  These two uses allow you to eliminate all
      built-in rules, or just certain style classes, so that your style file
      can start from a known rule base.

      Style class names are case sensitive, and all of the ones recognized
      by html-pretty must be spelled with lowercase letters.

      The style file is expected to contain lines of the forms:

           style-class : TAG1 TAG2 ...

           TAG : TAG1 TAG2 ...

           relationship[TAG] : TAG1 TAG2 ...

           -option
           -option -option ...
           -option value
           -option value -option value  ...

      In the second form, the style class of the first tag is looked up and
      assigned to the remaining tags.  That first tag must be entirely
      UPPERCASE in order to distinguish it from a style class.  The
      remaining tag names can be in either lettercase, or in mixed case;
      they will be converted to uppercase internally.

      The third form specifies a relationship between a tag, and one or more
      other tags.  The two currently-recognized relationships are
      ContainedIn and CannotContain; any others that are specified will
      simply be ignored, although they will take up memory space.  For
      example, the lines

           CannotContain[TITLE]      : LINK META SCRIPT STYLE
           ContainedIn[LH]           : DL OL UL

      mean that a TITLE environment cannot contain LINK, META, SCRIPT, or
      STYLE tags, and that an LH tag can only be contained in a DL, OL, or
      UL environment.   Unlike style class definitions, relationships are

      not cumulative; only the last one of each relationship type
      encountered for a particular tag will be used.

      Because of the complexity of SGML grammars, tag relationships cannot
      be reliably determined manually.  Instead, relationship tables are
      derived from the grammar files by software developed especially for,
      and included with, the html-pretty distribution, and then inserted
      into the standard style files.  Thus, it is not anticipated that users
      will provide tag relationship data in their personal style files,
      although they are free to do so.

      The built-in relationship tables are derived from a merger of the
      major grammar levels, so that they match tags in the built-in style
      classes, which are also derived from that merger.

      Tag relationships are only checked when the -check-tag-nesting option
      is specified, and since that is not a default option, omitting tag
      relationships will normally not have a visible effect on the output of
      html-pretty.

      In the remaining forms, command-line options appear, and any of the
      documented options may be used this way.  You can use this facility to
      collect preferred option settings in one place, such as in directory-
      or user-specific initialization files.  Observe that a -stylefile
      option here can be used to chain temporarily to another file, and this
      can go on recursively to a depth which is limited only by the run-time
      stack depth and the maximum number of simultaneously open files.

      Blank lines, leading and trailing whitespace, and text from a percent
      (%) comment character to end of line, are ignored.  To get a literal
      percent or quotation mark into a value, prefix it with a backslash;
      the backslash will be removed when the value is collected.

      Whitespace separates items, and can be omitted around the colon.
      There is no significance to the order of items on a line, or lines in
      the file, except that later settings can override earlier ones.  The
      same style class name may occur on multiple lines, and the tag lists
      will be accumulated, discarding duplicates.

      The line length limit in style files is system-dependent, but
      guaranteed to be at least 2048 characters.

      Here is an example of a small style file to add the new tags
      introduced in the HTML proposed 4.0 grammar (even though they are
      actually already present in the built-in rules):

           public : "-//W3C//DTD HTML 4.0 Transitional//EN"

      The last style class attached to command or environment name is the
      one that is used, so specifications in command-line -extend-style,
      -grammar-level, or -stylefile options can override those in the
      current directory style file, those in turn override settings from the
      home directory style file, and those override system-wide style file
      settings.

 CATALOG DIRECTORY
      The built-in style rules in html-pretty, together with the three
      default startup style files, and the -extend-style class: taglist and
      -stylefile stylefile options suffice for most uses of the
      prettyprinter.

      However, it may be useful to offer a simpler interface that only
      requires the user to specify the desired grammar level with the
      -grammar-level grammar option, and have html-pretty automatically find
      the style files.  Thus, when the -grammar-level option is used, html-
      pretty looks for a catalog directory that contains a file named
      catalog, and one or more style files.

      The catalog directory is searched for in the same path as the
      executable file, but in a path starting one level higher.  On UNIX, it
      is usually called share/lib/<programname>, so if the executable
      program was /usr/local/bin/html-pretty, the catalog directory is
      /usr/local/share/lib/html-pretty.  [Conventionally, on UNIX systems,
      directories in the share directory tree are shared across multiple O/S
      releases and vendor architectures.]

      On other operating systems, the share portion of the path may be
      omitted.  However, the quickest way to find out where the catalog
      directory resides on your system is to run html-pretty with the
      -grammar-level and -trace-opens options, to trace the file-opening
      attempts.

      The catalog file has a simple format: each non-empty line contains a
      grammar level, and a corresponding filename in that directory.  As
      with style files, comments run from percent (%) to end-of-line, but
      there is no support for line continuation, since the lines are all
      very short.  To get a literal percent or quotation mark into a value,
      prefix it with a backslash; the backslash will be removed when the
      value is collected.

      This indirect mapping of grammar level to style file means that end
      users need not know the style file names, and thus, that the names can
      be changed to meet local requirements.

      SGML parsers and other SGML software use a similar catalog file to map
      DTD descriptor strings to local filenames.

      Lettercase is not significant in grammar-level names, although it may
      be for filenames.  The standard style files are all named in a single
      lettercase, so that the catalog entries work on all file systems.

      If you are developing a new set of styles, you probably do not want
      them put in the system-wide catalog directory until they have been
      completed and debugged. In such a case, you can use the -catalogfile
      option to specify an alternate catalog file location.  Once they are
      ready for wider release, you (or your system manager) can merge your
      catalog file with the system one, and copy your style files into the
      system catalog directory.

 COMMENTS IN HTML AND SGML
      The SGML (and thus, HTML) comment syntax confuses many users,
      including browser programmers, and book writers, who either get it
      wrong, or fail to explain it properly.

      SGML has a command called markup declaration open, or mdo for short,
      which defaults to the two-character sequence <!, and is matched by a
      markup declaration close, or mdc, which defaults to the one-character
      sequence >.  The mdo must be immediately followed either by a keyword,
      such as ATTLIST, DOCTYPE, ELEMENT, ENTITY, NOTATION, SGML, SHORTREF,
      or USEMAP, or else by a comment start, which is the two-character
      sequence --.  In the latter case, there must later be a second -- pair
      to signal a comment end.  Anything after that second pair is non-
      comment text to be parsed.  However, additional comments can appear,
      provided that they are surrounded by -- pairs. Eventually, the markup
      declaration is ended by an mdc command, although whitespace may follow
      the last comment.  Thus,

           <!--one-- --two-- --three-->
           <!-- one -- -- two -- -- three -- >
           <!-- one --
             -- two --
             -- three --
           >

      are all legal markup declarations, each of which consists of three
      comments. However, these are in error:

           <! --one-- --two-- --three-- >
           <!-- one -- two -- three -- >
           <!--
                    one --
                 -- two --
                 - - three - -
           >

      The first has an illegal space after the mdo, the second has the word
      two outside a comment, and the third has the text - - three - -
      outside the comment.

      Given these rules, can SGML comments be nested?  It might appear that
      they can, since

           <!-- <!-- --> -->
           <!-- <!-- --> <!-- --> -->

      are both accepted by an SGML parser.  However, the nesting is
      illusory, since the first has two comments, containing the text <! and
      >, and the third has three comments: <! and > <! and >.  As soon as we
      put words between the hyphen pairs, such as

           <!-- one <!-- two --> three -->
           <!-- one <!-- two --> <!-- three --> four -->

      the word two lies outside the comment in the first, and two and three
      are outside the comment in the second.  Therefore, SGML and HTML
      comments cannot in general be nested.

      Finally, because of the special significance of -- as both a comment
      start and a comment end inside a markup declaration, you must be
      careful about using adjacent hyphens in the comment text.  In
      particular, if you use a line of hyphens to set off one block of text
      from another, the number of hyphens must be a multiple of 4, such as
      this 60-hyphen example:

           <!------------------------------------------------------------>

      Having 57, 58, 59, 61, 62, or 63 hyphens won't do!

      html-pretty does not distinguish markup declarations, beginning with
      <!, from tags, beginning with <, except for comments, which have to be
      parsed separately anyway to handle the pairs-of-pairs-of-hyphens
      balance requirement.  Thus, it considers !DOCTYPE to be a tag name,
      when strictly speaking, the ! is part of the markup declaration open.
      However, since the closing character > can always be represented by an
      SGML entity, &lt;, html-pretty can safely assume that anything between
      angle brackets is a `tag'.  That is why the style files have a rule

           doctype :            !DOCTYPE

      with the exclamation mark prefixed to the word DOCTYPE.

 HTML GRAMMAR CONSTRAINTS
      It is not immediately obvious from the HTML grammars just which tags
      can be contained in, or by, other tag environments.  The list below
      was automatically extracted from the HTML grammar files by software
      developed especially for, and included with, the html-pretty
      distribution.

      The grammar rules for some environments explicitly forbid certain tags
      from appearing in those environments; this is indicated in the lists



                                   - 27 -           Formatted:  July 3, 2022






 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



      below by the prefix cannot contain:.

      Because the HTML definition is evolving, many tags are defined only in
      certain grammar files. In such a case, the grammar level is indicated
      by a suffix with a colon and a sorted list of one or more levels: 2,
      3, 3.2, 4C (4-Cougar), 4L (4-loose), and M (Mosaic and Netscape).
      [The level 4-strict from July and November, 1997, is excluded because
      the grammar file omits many heavily-used tags, in anticipation that
      their features will be provided by style sheets.]

      Although there are other HTML grammar versions, these are the major
      ones that are important for current browsers.  If no grammar level
      list is present, then the tag is available in all of the levels listed
      at the start of this paragraph.

      The `tag' #PCDATA means parsed character data, an SGML term for text
      of zero or more ordinary characters and/or SGML named and numeric
      entities, such as &quot; and &#34;.

      The `tag' ANY is a catch-all that means #PCDATA, or any SGML tag
      defined in the grammar.  It should not be used in SGML grammars, but
      it is present in the Mosaic/Netscape grammar file, html-mcom.dtd.

      The `tag' CDATA means character data, an SGML term for zero or more
      characters that are not further examined, except for the purposes of
      scanning for an end tag.  This corresponds to verbatim text in
      typesetting and word-processing systems.

      The special `tag' EMPTY means that the environment is empty, and
      further, that a matching end tag is forbidden.

      If no end tag is shown in the paragraph heading, then it must be
      omitted in HTML files.

      Unless suffixed by optional, all tags listed in the remainder of this
      section are required.  However, if a grammar level list is attached to
      optional or required, then the tag is defined only in those grammar
      levels.

      Use these lists as a portability guide: if a tag is implemented in
      only specified grammar levels, then documents which use it are more
      likely to be displayed improperly by Web browsers.

           NB: The meaning of this tag is aberrant, in that the closing  tag
           is  not supposed to be present, even though the grammar says that
           it is optional: the environment  instead  terminates  at  end-of-
           file.   Browsers  differ  in  their handling of the end tag: some
           display it as ordinary text, and others  terminate  the  environ-
           ment.

 PRETTYPRINTER LIMITATIONS
      Like LaTeX, Lisp, PostScript, and TeX, SGML is an extensible language.
      In  particular, at run time, it is possible to redefine the syntax and
      semantics of all lexical elements, including the base  character  set,
      the characters that may appear in identifiers, and the special charac-
      ters that delimit tags or strings.

      In SGML, this is conventionally done in  SGML  declaration  files  for
      syntax  definitions,  and  in  DTD files, which are analogous to LaTeX
      style files.  Low-level typesetting commands of the flavor ``select  a
      14-point  Lucida-BoldItalic  font'', ``skip down vertically 6 picas'',
      and ``draw a horizontal rule 3 ems long'' are  notably  absent.   SGML
      documents are expected to use only high-level markup commands, leaving
      the visual appearance entirely up to the DTD  specification,  and  the
      formatting software.

      Unlike LaTeX and TeX, SGML is not a typesetting system.  It is only  a
      grammar  for  a  standard  markup  language,  and  it  is left to SGML

 HTML-PRETTY(1)                 Version 1.00                  HTML-PRETTY(1)
                              04 December 1997



      software implementors to write DTDs, and to provide for translation of
      SGML  documents  to specific document formatting, typesetting, or word
      processing systems.  In this respect, SGML is similar to the RTF (Rich
      Text Format) supported by many popular word processors, in that it can
      serve as an intermediate language for  electronic  document  exchange;
      several  language  translators between SGML and other text representa-
      tions are mentioned in the SEE ALSO section below.  Regrettably, there
      is  wide  variation in the capabilities and document models of current
      text formatting systems, so such translations are  usually  rough  ap-
      proximations  that  may require substantial hand patching to make them
      truly satisfactory.

      HTML is a modest subset of SGML, with tag names apparently chosen from
      SGML,  the Free Software Foundation's TeXinfo system (which in turn is
      modeled on the earlier Scribe document formatting system),  and  occa-
      sionally, also from LaTeX.

      html-pretty is written in this spirit: it knows about the meaning  and
      typical  use  of  all standard HTML tags, but nothing about other SGML
      DTDs.  However, the style-file facility makes it possible  to  prepare
      formatting  rules  for  any  SGML  DTD, extending the applicability of
      html-pretty to the entire world of SGML,  provided  a  tag  normalizer
      such  as  sgmlnorm(1)  or spam(1) is available to supply omitted tags,
      and expand abbreviated ones.  However, since SGML tag names depend  on
      the  specific DTD, and DTDs tend to be proprietary, html-pretty is not
      packaged with pre-written style files for SGML.

      Contributions of suitable style files for public SGML  DTDs,  together
      with those DTDs, are hereby solicited, and they may be included in fu-
      ture releases of html-pretty.

 PRETTYPRINTER IMPLEMENTATION LIMITS
      As with most computer  software,  there  are  certain  limitations  in
      html-pretty  on object sizes, imposed by fixed array dimensions or ad-
      dressing limits of the computer hardware and operating  system.   Here
      are  the minimum values that all html-pretty implementations must pro-
      vide in order to conform to  this  documentation;  implementations  on
      some systems may have much more generous limits.

           2048 characters in single words, tag names, and  filenames  (this
           must  be  at  least  as large as the LITLEN limit set in the SGML
           parser declaration file html.decl);

           100 levels of list and environment nesting (this must be at least
           as  large  as the TAGLVL limit set in the SGML parser declaration
           file html.decl);

           6 simultaneously open files (stdin, stderr, and stdout, plus  the
           style  catalog  file,  and two style files, allowing at least two
           levels of style file nesting).

      These are ample for any realistic document: they support  the  longest
      legal  file  paths  in all major current operating systems, World-Wide
      Web URLs, and HTML tags named after 58-letter Welsh towns  like  Llan-
      fairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, yet will still
      work on the smallest personal computer operating systems.

      There is no limit on the size of input or output files and lines, oth-
      er  than that imposed by physical storage limits of the host file sys-
      tem and the computer address space.
