 NAME
      xarchie - X11 browser interface to archie, version 2.0.9

 SYNOPSIS
      xarchie [X Toolkit options] [-host host]
              [-search type|-e|-c|-s|-r|-ec|-es|-er] [-sort type|-t|-w]
              [-maxhits num] [-offset num] [-nice lev|-N lev] [-noscroll]
              [-mono|-gray|-color] [-debug num|-D num] [-help|-?]

 DESCRIPTION
      Xarchie is an X11 browser interface to the Archie Internet information
      system   using  the  Prospero  virtual  filesystem  protocol.   Archie
      provides information about files available for  ftp  anywhere  on  the
      Internet;  Xarchie  displays  this  information  using an easy-to-use,
      point-and-click interface.  Xarchie allows you to further explore  ftp
      sites  by  examining directories returned as query matches, and allows
      you to retrieve files located this way.   Xarchie  is  designed  (like
      most X applications) to be highly customizable, allowing you to tailor
      the look-and-feel of the tool to your own preferences.

      This document is broken  into  two  parts.  First,  the  USER'S  GUIDE
      describes  Archie  and  Xarchie,  and  covers  both Basic and Advanced
      Xarchie  usage.  Second,  the  REFERENCE  MANUAL  provides   all   the
      information  needed  to  customize  Xarchie.  You can also browse this
      document using the Xarchie Help facility.

      To report problems or bugs, please see the section "Reporting Bugs" in
      the REFERENCE MANUAL section.

 USER'S GUIDE
      The User's Guide section of this manual describes the Archie  service,
      the  Xarchie  client,  and  how  to  use  Xarchie  to access resources
      available for FTP on the Internet.

  What is Archie?
      The Archie information system  is  a  network-based  information  tool
      offering  proactive data retrieval and indexing for widely distributed
      collections of data.

      Perhaps the best known application of the Archie system is to maintain
      the  Internet Archives database. This database, already available from
      a number of service providers across the Internet, currently  contains
      the  names of over 2,100,000 files at over 1,000 anonymous FTP archive
      sites.  Using this database, users can  rapidly  locate  needed  files
      without  the  need  to  log  onto dozens or even hundreds of machines.
      Archie servers offering this database currently  receive  over  50,000
      queries  per  day.   It  is  this  database  that  the  Xarchie client
      accesses, as described in the next section,  using  one  of  the  many
      independently owned and operated Archie servers around the world.

      The Archie system is much more than the  Internet  Archives  database.

  What is Xarchie?
      Xarchie is an X11 browser interface to the  Archie  Internet  Archives
      database  using  the  Prospero  virtual  filesystem  protocol.  Archie
      provides information about files available for  ftp  anywhere  on  the
      Internet;  Xarchie  displays  this  information  using an easy-to-use,
      point-and-click interface.  Xarchie allows you to further explore  ftp
      sites  by  examining directories returned as query matches, and allows
      you to retrieve files located this way.

      Xarchie  is  designed  (like  most  X  applications)  to   be   highly
      customizable,  allowing you to tailor the look-and-feel of the tool to
      your own preferences. See the REFERENCE MANUAL for details.

      Users should be aware that the Xarchie client accesses a  server  that
      is  shared  with  users  on  other hosts.  As such, submitting long or
      large numbers of queries during peak periods not  only  increases  the
      time  that  you have to wait for a response, but it increases the time
      that others have to wait too. Please read about the -nice option,  the
      niceLevel  resource,  and the "Nice Level" setting before making large
      queries.  Also, you should use  the  closest  possible  host  to  save
      long-distance  network  traffic. Abusers of the service may find their
      access revoked without notice.

  The Xarchie Display
      Xarchie uses several conventions regarding menus and button names:

      -    Clicking on a button whose name ends with a ">"  will  pop  up  a
           menu from which you should select the desired action.

      -    Clicking on or selecting an item whose name ends  in  "..."  will
           pop up a panel that will let you perform the desired operation.

      A label with neither of these suffixes indicates that the action  will
      be taken without subsequent interaction.

      Xarchie's display is divided into three horizontal areas. The top pane
      is a control panel providing the following buttons:

      File:
           Clicking on this button presents the File Menu,  from  which  you
           can  select  a variety of file-related operations to be described
           later. The File Menu operations can also be  invoked  by  holding
           down  the Meta key and typing the first letter of the operation's
           name (e.g., Meta-Q to quit).

      Settings:
           Clicking  on  this  button  presents  the  Settings  Menu,  whose

           operations will be described in the "Advanced Usage" section.

      Query:
           This button presents the Query Menu,  used  to  send  queries  to
           Archie.  Its operation will be described shortly.

      Abort:
           When active during a query or retrieval, this button  allows  you
           to abort the operation.

      Help:
           Clicking on this button pops up the Help Panel, which allows  you
           to  browse  this  document  on-line.   Finally, the area labelled
           "Status" is used to provide information about the progress  of  a
           query or other informative messages.

      The middle pane of the Xarchie display functions as  a  host-location-
      file  browser.  That  is,  the  leftmost  pane displays hostnames, the
      middle pane locations (directories), and the rightmost pane  files  or
      directories returned by a query. The browser's use is described in the
      section "Browsing", below. You can adjust the  relative  size  of  the
      browser panes using the Grips on their borders.

      Finally, the bottom pane of the Xarchie display provides a set of Text
      items  where  you  can  enter  information  and  where  information is
      displayed as query results are browsed. Not  all  Text  items  can  be
      typed  in;  some  are  used for display only. These text items provide
      Emacs-like editing controls (see xedit(1) for a complete description).
      Typing  Return  in some Text items invokes an action as a shortcut for
      selecting it from a menu or button.

  Basic Xarchie Usage
      This section provides information on  basic  querying,  browsing,  and
      file operations. The "Advanced Xarchie Usage" section describes how to
      use the Settings Panel and how to  perform  other,  more  complicated,
      queries.

   Querying
      The primary function provided by  Xarchie  is  that  of  querying  the
      Archie  server for a "search term" (the string or expression for which
      you want to search). By default, your query uses  exact  search  mode.
      That is, the search term must literally match an entry in the database
      for the entry to be returned. Other search modes  are  available,  and
      are described in the "Advanced Usage" section.

      You enter your search term in the appropriately labelled Text item  in
      the  bottom  pane  of the Xarchie display.  Hitting Return in the text
      item or selecting "Query Item" from the  Query  Menu  will  send  your
      request to Archie.

 XARCHIE(1)                    U of Rochester                     XARCHIE(1)
                                 24 Aug 1993



      The Status area will be updated as the  query  progresses.  First  the
      Archie  server's  Internet  address  is  looked up, then the server is
      contacted, the search term is sent over, and, after reaching the front
      of  the  server's  request queue, matches are returned to Xarchie. The
      matches, if any, are displayed in the  browser  and  the  Status  area
      indicates how many matches were returned.

      If your window manager and version of X support it,  you  can  iconify
      the  Xarchie  application  and  the  icon  will  change to reflect the
      progress of your query. That is, it will change when  a  query  is  in
      progress and when it finishes.

   Aborting
      If you find that your query is taking too long, you can  abort  it  by
      clicking  on  the "Abort" button when it is active. Your query will be
      aborted as soon as possible. You should note  that  while  aborting  a
      query  will  allow  you  to  enter a new query, it does not remove the
      query from the server's queue (this may be  changed  in  the  future).
      Thus  aborting  queries does not reduce the load on the server -- just
      the opposite probably. Use it with discretion, like the  rest  of  the
      service.

   Browsing
      As described in the section "The Xarchie Display", the middle pane  of
      the  Xarchie  display  functions as a host-location-file browser.  The
      leftmost pane of the browser contains the names of hosts that  have  a
      file  matching  your  search term. Clicking the Left mouse button on a
      hostname will highlight it and cause the middle  browser  pane  to  be
      filled with a list of locations on that host where files matching your
      search term can be found. The selected hostname will also be displayed
      in  the  Text  item  labelled "Host" in the bottom pane of the Xarchie
      display.

      Similarly, selecting a location from  the  middle  browser  pane  will
      cause  the  right  browser  pane to be filled with a list of the files
      available from the selected host in the  selected  location,  and  the
      location   will   be  displayed  in  the  bottom  pane  item  labelled
      "Location".

      Finally, selecting a file from the right browser pane causes its name,
      size,  permission  modes and last-modification date to be displayed in
      the correspondingly-labelled bottom pane items.

      Note that if a browser pane has only one item, then that item will  be
      automatically  selected  and  its "lesser" panes and information items
      filled in. This saves time and effort in the common case  where  there
      is  only  one  host,  location, or file that matches your query. Also,
      note that, by default, Xarchie  scrolls  the  browser  pane  when  you
      select  an  item.   This makes it easy to click through a long list of
      matches, but can be annoying. If you don't like it, it can be  changed
      on  the  Settings  Panel (described below), and see the description of

      the -noscroll command-line option in the REFERENCE MANUAL.

      The browser  allows  you  to  select  multiple  items  simultaneously,
      although  of  course  only  the  last-selected  item  will  have  it's
      information displayed in the bottom pane. You add to  a  selection  by
      clicking  the Left button with Shift depressed. If the clicked-on item
      is already selected, it will be unselected. Currently, only the bottom
      level  of  the browser can have multiple selections, since a selection
      at a higher level clears the selections for all lower levels (this may
      be  changed  in the future). Thus you can select multiple files from a
      single host, but not multiple files from separate hosts.

   Expanding the Browser
      The browser can be expanded,  allowing  you  to  investigate,  say,  a
      directory  that matched your query. To select and expand an directory,
      double-click on it (double-click with Shift to avoid  unselecting  any
      other  items). You can also select "Open" from the File Menu to expand
      directories (although this will also open selected files, as described
      later).  All  selected  directories  will  be  expanded by querying an
      appropriate Archie server, and the Status area will keep you informed.
      Expansion  requests can be aborted just like queries using the "Abort"
      button.

      If only  a  single  item  was  expanded,  and  if  the  expansion  was
      successful,  then  the browser will scroll to display the results. The
      arrow buttons across the top of the browser can be used to scroll  the
      browser left or right when they are active. The Middle and Right mouse
      buttons or the Left and Right arrow keys will do the same thing,  when
      the pointer is in the browser panes.

   Viewing Files
      You can view a file that is  selected  in  the  browser  by  selecting
      "Open"  from  the  File Menu (or by typing Meta-O).  Xarchie retrieves
      all selected files in ASCII mode  into  a  temporary  directory.   The
      Status  area,  like usual, will keep you posted on the progress of the
      operation and, once the  FTP  connection  is  established,  the  Abort
      button  can  be  used  to  abort the Open operation.  If you abort and
      there are files remaining to retrieve, you  will  be  prompted  as  to
      whether  to continue with the next file. Note that partially-retrieved
      files are not removed.   There  is  currently  no  way  to  abort  the
      transfer  until  the  connection  is  established. The connection will
      eventually timeout and control will return to Xarchie if connection is
      impossible.

      Each file is displayed in a popup Text window after  being  retrieved.
      Use  the  "Down"  and "Up" buttons or the scrollbars to view the text.
      Click on the "Dismiss" button to destroy the  window  and  delete  the
      file.  To save the file before dismissing, use the "Save" button. This
      pops up a panel with which you can choose the  name  of  the  file  to
      which to save.

      Note that because the Archie database is  only  updated  periodically,
      some  files  returned  by  Archie  may  not  exist when you attempt to
      retrieve them. This and any other FTP errors are signalled with  alert
      boxes.

   Retrieving Files
      The "Open" action should be used to view short files, such as "README"
      files,  that you don't need to save. For more permanent files, and for
      non-ASCII files like tar or compressed files, Xarchie  allows  you  to
      retrieve  the  selected browser items using the "Get" item of the File
      Menu (or typing Meta-G). The selected files are retrieved via FTP  and
      stored  in  the current directory (see the section "FTP Parameters" in
      the "Advanced Usage" section for how to change  this).   The  "Status"
      area  is  updated  to  reflect  the  progress  of the transfer. As for
      "Open", you can abort the retrieval using the "Abort" button once  the
      FTP connection is established.

      It is currently not possible to  retrieve  a  directory,  although  of
      course  the  directory  can be opened and the entire contents selected
      for transfer.

      Note that because the Archie database is  only  updated  periodically,
      some  files  returned  by  Archie  may  not  exist when you attempt to
      retrieve them. This and any other FTP errors are signalled with  alert
      boxes.

      As with querying, if your window manager and version of X support  it,
      Xarchie's icon will be changed to reflect the progress of a transfer.

   Saving, Loading, and Writing
      Xarchie allows you to save and reload the contents of the browser,  or
      write  it  in  human-readable format using the items on the File menu.
      Selecting either of "Save", "Load",  or  "Write"  (or  typing  Meta-S,
      Meta-L, or Meta-W, respectively) will pop up the File Panel with which
      you can specify the appropriate filename.  Clicking on the "Ok" button
      will  invoke  the appropriate action; clicking "Cancel" will abort the
      operation and pop down the panel.

      Saving the database creates a file containing  sufficient  information
      for  the  browser  to  be  reloaded  using  "Load".  The output is not
      intended for human consumption. The current Settings are also  written
      to the file by "Save" and are restored by "Load".

      Users should note that a reloaded database will be  "flattened",  that
      is,  directories  will  be  added  to the middle pane as needed to fit
      everything in three browser panes.  (This may be changed in the future
      to preserve the original hierarchy.)

      Writing the database is intended to create files that are more or less
      human-readable  (compared  to  "Save", anyway). There are two possible
      formats, selectable from the "Write Format" menu on the panel. If "One

      entry, in the format

                        mode size date host:location/file

      If "Pretty-printed" is selected, then the file  format  has  hostnames
      starting  at  the  beginning  of the line, location names indented one
      tab, and file entries  indented  two  tabs,  all  on  separate  lines.
      Hostnames and locations are only printed once, as in:

              host
                      location
                              mode size date file
                              mode size date file

      The latter is more readable, the former may  be  more  useful  if  the
      output is to be used by a program.

   Quitting Xarchie
      You can exit Xarchie by selecting "Quit" from the File Menu (or typing
      Meta-Q).

  Advanced Xarchie Usage
      This section describes how various aspects of Xarchie's  functionality
      can  be  modified  to  perform different queries and other operations.
      Further customization information is found  in  the  REFERENCE  MANUAL
      section.

   The Settings Panel
      The panel popped up by selecting "Other" on the Settings Menu  in  the
      top  Xarchie  pane allows you to change the parameters of your queries
      Archie. Each of the parameters is described in the following sections.

      After you're done with the Settings Panel,  clicking  on  the  "Apply"
      button  will  make  Xarchie  use  the  settings  as  set on the panel.
      Clicking on "Default" will reset the settings to the values  they  had
      when  Xarchie started (but note that you will still have to apply them
      to have them take effect). Clicking  on  "Done"  closes  the  Settings
      panel.  A  popup  confirmer  will  appear  if  you  did not apply your
      changes, allowing you to discard the changes  or  go  back  and  apply
      them. Note that the "Apply" button is inactive until a change is made.

      The menus available from the "Search Type", "Sort Type", "Nice  Level"
      and  "Archie Host"  submenus  of  the Settings Menu on the Xarchie top
      pane have effects  corresponding  to  those  of  the  buttons  on  the
      Settings  Panel.  However, they do not require that the "Apply" button
      be clicked on to take effect, and do not affect the behaviour  of  the
      "Done" button confirmer.

      The item labelled "Host" provides a menu of known  Archie  hosts.  You
      should  choose  one appropriate to your site (i.e., one that minimizes
      long-distance transmission).  In addition however, you  can  enter  an
      arbitrary  hostname  in the Text item next to the "Host" button.  Note
      that the Archie host is only used for queries; expansion requests  use
      information  stored with the items to determine which host to contact.
      That is, changing the Archie host does not  "take  effect"  until  the
      next query is issued.

      If you have the ping(1) program, you can try to use it  with  the  its
      "-s" option to locate a "nearby" host.

      You can specify hostnames using either the symbolic name or by  giving
      its  numeric  IP address (four octets separated by periods). In either
      case, you can specify the port at which the Prospero server should  be
      contacted  by  giving  it  in  parentheses  immediately  following the
      hostname (no spaces).

   Search mode
      The "Search Mode" item allow you to change how Archie interprets  your
      search term.  Holding a mouse button down while the mouse cursor is on
      the button displays a menu from  which  you  can  choose  the  desired
      search type.  The label to the right of the item is updated to reflect
      the choice.

      The exact mode is fastest and  returns  files  exactly  matching  your
      search  term.  The substr and subcase modes return substring and case-
      sensitive substring matches respectively  (i.e.,  substr  means  case-
      insensitive).  The  regexp  mode  allows  you  to  specify  a  regular
      expression to select files (see ed(1) for  a  description  of  regular
      expression syntax).  The exact* forms of these last three try an exact
      match first and then fall back on the more costly search type  if  the
      exact match fails.

   Sort mode
      The "Sort Mode" item allows you to specify how  Xarchie  displays  the
      results  from  Archie.   Holding  a  mouse button down while the mouse
      cursor is in this item displays a menu from which you can  choose  the
      desired  sort  type.  The label to the right of the item is updated to
      reflect the choice.  Applying the settings (see above) will cause  the
      data to be resorted according to the new sort mode.

      The type can be one of name, date, or  weight.   Sorting  by  name  is
      simple lexicographic ordering.

      If sorting by date is selected, then hosts are  ordered  according  to
      the  most recent file among those returned for them, and similarly for
      locations. Files themselves are  ordered  by  last-modification  date,
      naturally.

      If sorting by weight is selected, then hosts are ordered  by  a  user-
      definable  set  of  "weights". In this way, hosts that are "close" (in
      some sense) are displayed first. The weights can be set using the Text
      item  that  appears  on  the  Settings  Panel  when  this sort mode is
      selected.

      Hopefully, an appropriate weight list for the geographic  location  of
      your  site  will  have been installed as the default. In any case, the
      the weight list is a set of lines, where each line specifies a  weight
      and  the set of domains for that weight. A host's weight is determined
      by finding the first line for which the end of the host's name matches
      one  of  the  suffixes.  A host that belongs in none of the classes is
      assigned the weight 99. For example, the default for the USA is:

             1 edu com net gov mil us\n\
             2 ca\n\
             3 uk de nl fi fr eu.net\n\
           100 au nz jp

      This means that all the US domains are  ordered  first,  then  Canada,
      then  several European countries. Hosts in Australia, New Zealand, and
      Japan are ordered after any unknown (i.e. non-matching) hosts.

      For more details, see the description of  the  hostWeights  non-widget
      resource in the REFERENCE MANUAL section.

   Nice level
      The "Nice Level" item deserves special mention. As  mentioned  in  the
      "About  Archie"  section,  Archie servers run on machines that must be
      shared between other Archie users and even other  "real"  users.  This
      item  allows  you  to  voluntarily lower the priority of your request,
      just like the nice(1) command does for Unix. The  menu  provides  some
      recommended  values  and  you  can  enter arbitrary values in the text
      item. If you are searching with a large number of  matches  requested,
      please increase your nice level.

      Note that, like nice(1), nicing a job does not  mean  your  job  won't
      affect  others.   In  particular,  once your job begins it is not pre-
      empted, thus you should still avoid long jobs during peak periods. You
      should  especially  avoid  queries for items of only personal interest
      (you know what we mean) during these periods. As stated above, abusers
      of the service may find their access revoked without notice.

   Other Query Settings
      The following items set parameters of your query to the Archie server.

      Max Hits:
           the limit on the  number  of  successful  matches  that  will  be
           returned.

      Initial Timeout:
           the length of the first timeout interval in seconds.

      Retries:
           the number of times to retry a query if it  times  out,  doubling
           the timeout each retry.

      These items are Text items that allow you to edit their values.

      The item labelled "Auto-Scroll Browser" controls whether  the  browser
      scrolls  after  an  item  is selected. Setting this to "yes" is useful
      when browsing a long list of matches. It can  be  annoying  if  you're
      doing more selective browsing, so set it to "no" in those cases.

   FTP settings
      The following items allow you to set parameters of file retrieval. You
      should  be  sure  they  are  appropriately set before retrieving files
      using either "Open" or "Get".

      FTP Email Address:
           Specifies  the  password  used  for  anonymous  FTP   login.   By
           convention,  users  logging  in  as  "anonymous" send their email
           address as the password. Some servers enforce  this  by  checking
           the address. The default may not be appropriate depending on what
           information Xarchie  could  glean  from  your  system  about  its
           address.  You can set the environment variables USER and HOSTNAME
           to override the system's information, or see the  description  of
           the ftpMailAddress non-widget resource in the REFERENCE MANUAL.

      FTP Local Directory:
           Specifies the directory into which files will be retrieved  using
           "Get".

      FTP Transfer Type:
           Provides a menu from which you can  select  "ascii"  or  "binary"
           mode  transfer  for  files  retrieved with "Get". Files retrieved
           with "Open" are always retrieved in ascii mode.

      FTP Prompt:
           Provides a menu allowing  you  to  enable  or  disable  prompting
           during multi-file transfers.

      Trace FTP Transfers:
           Since  FTP  transfers  are  susceptible  to  timeouts  and  other
           confusions, this item allows you to monitor any FTP interactions.
           If tracing is enabled, then invoking "Open" or "Get"  on  a  file
           will  popup a trace window that displays a running log of the FTP
           session as it happens.  Using this successfully requires that you
           understand  something  about  how  FTP works, which is beyond the
           scope of this document.

      Strip CR
           If this option is enabled, then carriage returns are removed from
           ASCII-mode  files. This is usually desirable when transferring to
           a Unix machine.

   Querying Hosts and Locations
      The Query Menu provides two other types of queries besides the  "Query
      Item"  described  in the "Basic Usage" section for querying the Archie
      database.

      Selecting "Query Host" will use the hostname in the "Host"  Text  item
      on  the bottom pane and will fill the browser with the contents of the
      root of its FTP directory. From then on, interaction is as  previously
      described.  The host to query can be in the "Host" item as a result of
      selecting a host in the browser, or you can  type  directly  into  the
      item  the name of the host that you wish to open. Typing Return in the
      "Host" item is equivalent to selecting "Query  Host"  from  the  Query
      Menu.

      Querying locations by  selecting  "Query  Location"  is  similar:  the
      Archie  server  is  queried for the contents of the directory given by
      the "Location" item on the host given by the "Host" item. The  browser
      is  filled in with the results of the query (i.e., the contents of the
      directory). As before, you can type the name of the location into  the
      "Location"  item  if  you wish, and typing Return there is the same as
      invoking "Query Location".

      Note that because the Archie database is  only  updated  periodically,
      some  files  returned  by  Archie  may  not  exist when you attempt to
      retrieve them. Similarly, recently added files may exist on  the  host
      but not in the Archie database.

 REFERENCE MANUAL
      This section provides all the information you should need to customize
      Xarchie.    Command-line   options,   non-widget   resources,   widget
      hierarchies, translations  actions,  and  other  information  are  all
      provided.   It   is   assumed  that  you  understand  enough  about  X
      applications to understand this.

  Command-line Options
      The following non-widget resources can be set from the command-line or
      in  a resource file. As usual, when given on the command line they can
      be abbreviated to  their  shortest  unique  prefix,  often  the  first
      letter.   Furthermore  Xarchie  accepts  all  the  standard  X Toolkit
      options (see X(1)).

      -host host
           Sets the host to which Archie queries will  be  sent.  Please  be
           careful  to  use  the  nearest  possible  host.   You can specify
           hostnames using either the symbolic name or by giving its numeric
           IP  address  (four  octets separated by periods). In either case,

           you can specify the port at which the Prospero server  should  be
           contacted  by  giving it in parentheses immediately following the
           hostname (no spaces).

           The default is "archie.sura.net(1526)". This  option  corresponds
           to the archieHost resource.

      -search type
           Sets the search mode for Archie queries. The type can be  one  of
           exact,  substr,  subcase,  regexp,  exactSubstr, exactSubcase, or
           exactRegexp.  See the section describing the  Settings  Panel  in
           the  USER'S  GUIDE for a description of the various search types.
           The default search mode is exact.  This option corresponds to the
           searchType resource.

      -e   Equivalent to "-search exact".

      -s   Equivalent to "-search substr".

      -c   Equivalent to "-search subcase".

      -r   Equivalent to "-search regexp".

      -es  Equivalent to "-search exactSubstr".

      -ec  Equivalent to "-search exactSsubcase".

      -er  Equivalent to "-search exactRegexp".

      -sort type
           Sets the sort mode for displaying Archie responses. The type  can
           be  one of name, date, or weight.  See the section describing the
           Settings Panel in the USER'S  GUIDE  for  a  description  of  the
           various  sort  types.   This  option  corresponds to the sortType
           resource.

      -t   Equivalent to "-sort date".

      -w   Equivalent to "-sort weight".

      -maxHits num
           Sets the maximum number of matches allowed per query. This option
           corresponds to the maxHits resource.

      -offset num
           Sets the offset of the Prospero query. This option corresponds to
           the offset resource.

      -nice level or -N level
           Sets the query niceness level. Higher numbers are nicer, up to  a
           maximum niceness of 32765. The default niceness is 0. This option

           corresponds to the niceLevel resource.

      -noscroll
           By default, Xarchie scrolls the browser lists automatically  when
           you  select  items.  This usually makes it easier to scan through
           the results of queries but can be annoying. This option turns off
           the   automatic  scrolling.  It  corresponds  to  the  autoScroll
           resource.

      -mono or -gray or -color
           By default, Xarchie  will  determine  the  visual  type  of  your
           display  and use the proper color resources. If it gets it wrong,
           you can override the default by specifying one of these  options.
           They correspond to the visualType resource.

      -debug level or -D level
           Sets the Prospero  debugging  level.  Higher  numbers  mean  more
           verbose  messages.   This  option  corresponds  to the debugLevel
           resource.  Xarchie must be specially compiled for this option  to
           have any effect (see the Imakefile or your local installer).

      -help or -?
           Prints the usage message summarizing Xarchie options.

  Non-widget Resources
      Xarchie has a default set of  resources  built  in.  If  you  wish  to
      customize  the  tool,  take a copy of the default application defaults
      file (see the section "Files", below)  and  modify  it.  Then,  before
      invoking  Xarchie,  set  the  environment  variable XAPPLRESDIR to the
      directory containing your private copy. Alternatively, you  can  place
      entries  in your .Xdefaults file or provide them with the -xrm toolkit
      option (see X(1)).  Most of the following resources can  also  be  set
      using the command-line options described in the previous section.

   Query Resources
      archieHost
           Sets the host to which Archie queries will  be  sent.  Please  be
           careful  to  use  the  nearest  possible  host.  The  default  is
           "archie.sura.net".  This resource  can  be  set  with  the  -host
           option or on the Settings Panel.

           You can specify hostnames using either the symbolic  name  or  by
           giving its numeric IP address (four octets separated by periods).
           In either case, you can specify the port at  which  the  Prospero
           server   should   be   contacted  by  giving  it  in  parentheses
           immediately following the hostname (no spaces).

      searchType
           Sets the search mode for Archie  queries.  This  can  be  one  of
           exact,  substr,  subcase,  regexp,  exactSubstr, exactSubcase, or
           exactRegexp.  See the section describing the  Settings  Panel  in

           the  USER'S  GUIDE for a description of the various search types.
           The default search mode is exact.  This resource can be set  with
           the  -search  option,  or  its abbreviations -e, -s, -c, -r, -es,
           -ec, or -er, or on the Settings Panel.

      sortType
           Sets the sort mode for displaying Archie responses. This  can  be
           one  of  name,  date, or weight.  See the section of the Settings
           Panel, above, for a description  of  the  various  search  types.
           This   resource  can  be  set  with  the  -sort  option,  or  its
           abbreviations -t or -w, or on the Settings Panel.

      hostWeights
           Specifies the weights used to order hosts when sorting by  weight
           is  selected.  The format of this resource is a series of entries
           of the form:

                             weight host [hosts...] {,|\n}

           where parts of an entry are  separated  by  spaces  or  tabs  and
           entries  are  separated  by  a  comma  or  newline.   Each  entry
           specifies a weight and a series of possible suffixes (one or more
           trailing  components).  A  host's weight is determined by finding
           the first class for which the end of the host's name matches  one
           of  the  suffixes.  A host that belongs in none of the classes is
           assigned the weight 99. For example, the default for the USA is:

                  1 edu com net gov mil us\n\
                  2 ca\n\
                  3 uk de nl fi fr eu.net\n\
                100 au nz jp

           This means that all  the  US  domains  are  ordered  first,  then
           Canada,  then several European countries. Hosts in Australia, New
           Zealand, and Japan are  ordered  after  any  unknown  (i.e.  non-
           matching) hosts. This resource can be set on the Settings Panel.

           If this resource is not defined, Xarchie will attempt to make  an
           intelligent choice by comparing the system's idea of its hostname
           with a set of pre-compiled defaults. This may not  work,  but  is
           usually  better  than nothing, and it can always be edited on the
           Settings Panel anyway.

      niceLevel
           Sets the query niceness level. Higher numbers are nicer, up to  a
           maximum niceness of 32765. The default is 0. This resource can be
           set with the -nice option or on the Settings Panel.

      maxHits
           Sets the maximum number of matches allowed per query. The default
           is  99.   This resource can be set with the -maxHits option or on

           Sets the initial timeout value, in seconds.  The  default  is  4.
           This resource can be set on the Settings Panel.

      retries
           Sets the number of  retries,  where  the  timeout  doubles  every
           retry.  This resource can be set on the Settings Panel.

      debugLevel
           Sets the Prospero  debugging  level.  Higher  numbers  mean  more
           verbose  messages.  Xarchie must have been compiled specially for
           this option to have any effect (see the Imakefile or  your  local
           installer).  This  resource  can  be  set  with  the -debug or -D
           options.

   Browser Resources
      autoScroll
           By default, Xarchie scrolls the browser lists automatically  when
           you  select  items.  This usually makes it easier to scan through
           the results of queries but can be annoying. This resource enables
           or disables automatic scrolling.  The default is True.  It can be
           set to False with the -noscroll option and can be changed on  the
           Settings Panel.

      pasteBuffer
           If this resource is True (the default),  browser  selections  are
           stored  in  the  CUT_BUFFER_0  property of the root window of the
           Xarchie display in the format:

                                  host:location/file

           This  allows  them  to  be  used  by  other  applications   using
           XFetchBytes(3X).   The  Xarchie  distribution  includes  a sample
           program (xcutbuf.c) that retrieves the contents  of  a  cutbuffer
           property.

   FTP Resources
      ftpMailAddress
           By convention, FTP users are expected to send their email address
           as  the password during anonymous login.  The string specified by
           this resource is passed to sprintf(3) along with two  parameters:
           the  username  and the hostname (as indicated by the system or by
           the USER and HOSTNAME environment variables), and the  result  is
           used  as  the  password  for anonymous FTP logins. The default is
           "%s@%s". You should change this resource if your  system  returns

           (after sprintf) can be edited on the Settings Panel.

      ftpLocalDir
           Sets the local destination directory for ftp transfers. This will
           be  used  as the initial value of the "FTP Local Dir" item on the
           Settings Panel.

      ftpType
           Sets the transfer type for ftp transfers. This will  be  used  as
           the initial value of the "Ftp transfer type" item on the Settings
           Panel.  It should be one of "ascii" or "binary".

      ftpPrompt
           Specifies whether to prompt  for  verification  during  transfers
           involving  multiple files. This will be used as the initial value
           of the "Prompt during transfers" item on the Settings Panel.

      ftpTrace
           Specifies whether to pop up a window in  which  FTP  transactions
           are  monitored.  This  will  be  used as the initial value of the
           "Trace FTP transfers" item on the Settings Panel.

      ftpStrip
           Specifies  whether  to  strip   carriage   returns   from   files
           transferred  in  ASCII  mode.   This  will be used as the initial
           value of the "Strip CR" item on the Settings Panel.

   Database Writing Resources
      fileWriteOnePerLine
           Specifies the format of files written by "Write".  This  will  be
           used  as the initial value of the "Write format" item on the File
           Panel.  The meaning of this setting is described  in  the  USER'S
           GUIDE section on "Saving, Loading, and Writing".

   Special Font Resources
      Xarchie uses two fonts  by  default:  one  "normal"  and  one  "bold".
      However,  because  of  widget  naming and resource lookup conventions,
      these fonts must be specified in many places in the resource file.  To
      make  it  easier  to  find  and  change these fonts, the following two
      resources are defined:

      xarchieFont
           The name of the default font used  by  Xarchie  widgets.  If  any
           widget specifies a font resource as "xarchieFont", this font will
           be used.

      xarchieBoldFont
           Like the above, but specifies the font used by  any  widget  that
           specifies a font resource of "xarchieBoldFont".

                                 24 Aug 1993



      The resource converter that looks up fontnames is modified so that the
      the  two special strings "xarchieFont" and "xarchieBoldFont" result in
      the corresponding font being returned; other strings are looked up  as
      normal fontnames.

   Other Resources
      visualType
           This  resource  allows  you   to   override   Xarchie's   builtin
           determination  of  the  type of display, which it uses to specify
           appropriate color resources. You can specify  "mon",  "gray",  or
           "color"  as  the  value of this resource. It can also be set with
           the corresponding command-line options.

      defaultIcon
           If given, this resource specifies the name of an  X  bitmap  file
           that  will  be used as Xarchie's icon when not querying (assuming
           you are using a window manager that supports icon pixmaps). The X
           resource  conversion routines will look for the file in a variety
           of places, including directories given  by  the  global  resource
           bitmapFilePath.

      busyIcon
           If given, this resource specifies the name of an  X  bitmap  file
           that  will  be  used  as  Xarchie's  icon  when querying (see the
           description of the defaultIcon  resource,  above).  The  icon  is
           changed  back to the default when the query completes, so you can
           watch for a change while Xarchie is iconified.

  Widget Hierarchies
      Xarchie uses primarily Athena widgets, with some extra sub-classes  as
      described below.

   Main Xarchie Widgets
      The widget hierarchy for the main Xarchie display is as follows:

      Xarchie xarchie
        [Form color|gray] <-- Color or gray-scale displays only
           Paned outerPaned
                Form buttonForm

                          Viewport browserViewport1
                               XfwfMultiList browserList1
                          Viewport browserViewport2

                     Label,Text modes{Label,Text}
                     Label,Text date{Label,Text}

      On color displays, there is an extra Form widget named "color" created
      as  the  only  child  of the toplevel shell, and all other widgets are
      children of it. This allows resources that  are  only  applicable  for
      color  displays  to  use  the  prefix  "Xarchie.color" while generally
      applicable resources should use the "Xarchie*" prefix.  On  gray-scale
      displays, the extra widget is named "gray". On monochrome displays, no
      extra widget is created.

      The XfwfMultiList widget is a modification of the standard Athena List
      widget  that  allows  multiple items to be selected. It was written by
      Brian Totty (totty@flute.cs.uiuc.edu) and is distributed by  the  Free
      Widget  Foundation  (contact  free-widgets-request@kazoo.cs.uiuc.edu).
      Xarchie can be compiled to use standard Athena List  widgets  instead.
      See the Imakefile or your local installer.

      To describe this widget hierarchy  briefly,  outerPaned  controls  the
      relative   sizes   of   the   three  horizontal  display  areas  while
      browserPaned allows the browser panels to  be  resized  independently.
      Each browser panel consists of a Viewport to allow it to scroll and an
      XfwfMultiList (or List) to display the entries.

      The command buttons and status widgets are pretty straightforward. The
      fileButton  pops  up  the  fileMenu,  whose  items  invoke the obvious
      actions (see below) when selected.  The  settingsButton  pops  up  the
      settingsMenu,   which   uses   some   special   translations  and  the
      settings-submenu() action to permit the use of pullright submenus. The
      queryButton  pops  up  the  queryMenu,  the  abortButton (when active)
      invokes the abort() action, and  the  helpButton  invokes  the  help()
      action to pop up the Help panel.

      In the bottom pane, the searchText widget is used to enter the  search
      term, and by default it binds Return to the query() action (see below)
      to  send  the  query  to  Archie.   The  hostText  binds   Return   to
      query-host()  and  the  locationText binds Return to query-location().
      All the other Text items in the stringForm cannot be  edited  and  are
      used to display information about the current browser selection.

   Settings Panel Widgets
      The "Panel" item on the Settings menu  pops  up  the  Settings  Panel,
      which has the following widget hierarchy:

           TopLevelShell settingsShell
                Form settingsForm
                     Command setDoneButton
                     Command setApplyButton
                     Command setDefaultButton
                     MenuButton,AsciiText setHost{Button,Text}

                     Label,AsciiText setMaxHits{Label,Text}
                     Label,AsciiText setTimeout{Label,Text}
                     Label,AsciiText setRetries{Label,Text}
                     Label,AsciiText setAutoScroll{Button,Label}
                     Label,AsciiText ftpMailAddress{Label,Text}
                     Label,AsciiText ftpLocalDir{Label,Text}
                     MenuButton,Label ftpType{Button,Label}
                     MenuButton,Label ftpPrompt{Button,Label}
                     MenuButton,Label ftpTrace{Button,Label}
                     MenuButton,Label ftpStrip{Button,Label}

      The   setDoneButton   invokes   the   settings-done()   action,    the
      setApplyButton  invokes  settings-apply(),  and  the  setDefaultButton
      invokes settings-default().  The actions  are  described  below.   The
      MenuButton  widgets  pop  up menus described below under "Menus".  The
      AsciiText widgets are used  to  display  and  edit  the  corresponding
      parameters.

   File Panel Widgets
      The "Save", "Load", and "Write" items on the File menu pop up the File
      panel, which has the following widget hierarchy:

      TopLevelShell fileShell
           Form fileForm
                Label fileLabel
                XfwfFileChooser fileChooser
                Label,AsciiText filename{Label,Text}
                MenuButton,Label fileWriteMode{Button,Label}
                Command fileOkButton, fileCancelButton


      The XfwfFileChooser widget provides a  browser  for  selecting  files.
      Xarchie  can  be  compiled without the FileChooser, if necessary.  See
      the Imakefile or your local installer.

      In  any  event,  the  fileLabel  indicates  what  operation  is  being
      performed, the fileChooser, fileText, and buttons are used to select a

      file, and the fileWriteModeButton pops up the fileWriteModeMenu  (only
      enabled  for  Write). Typing Return in the filenameText is the same as
      clicking the fileOkButton, and sending  the  WM_DELETE_WINDOW  message
      (typically  from  the  window  manager) is the same as clicking on the
      fileCancelButton.

   View Window Widgets
      Whenever a file is retrieved by "Open", it is displayed  in  a  window
      with the following widget hierarchy:

      TopLevelShell viewShell
           Form viewForm
                Command viewDoneButton
                Command viewDownButton
                Command viewUpButton
                Command viewSaveButton
                Text viewText

      The title of the TopLevel shell is set to the  basename  of  the  file
      being  viewed  in  the  viewText.  The operation of the buttons is all
      hard-coded.  Clicking on the viewSaveButton results in  the  following
      panel being displayed to select the file to save to:

      TopLevelShell viewSaveShell
           Form viewSaveForm
                Label viewSaveLabel
                AsciiText viewSaveLabelText
                XfwfFileChooser fileChooser
                Label viewSaveTextLabel
                AsciiText viewSaveText
                Command viewSaveOkButton, viewSaveCancelButton

      The viewSaveLabelText indicates the name of the  temporary  file  from
      which  the  save should be made and connot be changed. The fileChooser
      and fileText allow you to select the file to save to.

   Help Panel Widgets
      The "Help" button in Xarchie's top pane pops up the Help panel,  which
      has the following widget hierarchy:

      TopLevelShell  helpShell
           Form  helpForm
                Label  helpLabel
                Viewport  helpViewport

                Text  helpText
                Command  helpDoneButton
                Command  helpPrevButton
                Command  helpNextButton
                Command  helpDownButton
                Command  helpUpButton

                                 24 Aug 1993



      The  helpLabel  identifies  the  version  of  Xarchie.   The  helpList
      displays  the  help topics, and the corresponding text is displayed in
      the helpText.  The helpDoneButton invokes the help-done() action,  the
      helpPrevButton  invokes the help-prev() action, and the helpNextButton
      invokes the help-next() action. The  helpDownButton  and  helpUpButton
      invoke the help-down() and help-up() actions respectively.

   About Panel Widgets
      Selecting the "About" item on the File menu pops up the  About  panel,
      which has the following widget hierarchy:

      TopLevelShell aboutShell
           Form aboutForm
                Label aboutLabel{0,1,2,3,4,5}
                Command aboutDoneButton

      The labels are set to display the version of Xarchie and other contact
      information. There is little you can or should do with these widgets.

   Popup Widgets
      Finally, two types of popup windows can appear. An Alert  box  signals
      an error and blocks until clicked in; a Confirm box allows the user to
      make a Yes/No decision. These have the following widget hierarchies:

      TransientShell alertShell
           Dialog alertDialog
                Command okButton

      TransientShell confirmShell
           Dialog confirmDialog
                Command yesButton,noButton

      respectively. Several actions are defined (see below) for use in these
      popups.

   Menus
      The MenuButton widgets on both the main Xarchie  display  and  on  the
      various  panels  use standard Athena SimpleMenu widgets. The following
      naming conventions are used to allow resources to be specified: if the
      parent  SimpleMenu  widget  is named "fooMenu", then the SmeBSBObjects
      making up the entries are named "fooMenuItemn", where n  starts  at  0
      for the first item in the menu. The menus are all children of the main
      Xarchie shell, toplevel.   For  example,  the  File  menu  has  widget
      hierarchy

      SimpleMenu  fileMenu
           SmeBSB  menuLabel
                SmeBSB  fileMenuItem{0,1,2,3,4,5,6}

      There are three things worth mentioning. First, as  noted  above,  the
      settingsMenu  uses  special  translations  and  the settings-submenu()
      action to allow pullright submenus. Secondly, the  submenus  available
      from  the Settings menu (searchMenu, sortMenu, niceMenu, and hostMenu)
      and those available on the Settings Panel (setSearchMenu, setSortMenu,
      setNiceMenu,  and  setHostMenu) have the same labels but are different
      widgets with different effects.  The Settings Panel menus (the  second
      group) only update the Settings panel, requiring the Done button to be
      clicked to take effect. The Settings menu submenus (the  first  group)
      take  effect  immediately,  and  also indicate the current item in the
      left margin of the menu.

      Finally, the number, order, and effect of  all  menus  are  hardcoded,
      although  the  labels can, of course, be changed in the resource file.
      However, changing the labels will NOT change the effect  of  selecting
      the  item,  with the exception of the hostMenu and setHostMenu.  These
      menus use the numHosts non-widget resource to indicate how many  items
      are  on  the  menu. Thus you can add hosts to the menu by adding label
      resources for the new  hostMenuItem's  and  increasing  the  value  of
      Xarchie.numHosts.    Xarchie   parses  the  labels  to  determine  the
      hostname: anything up to  whitespace  constitutes  the  hostname  (and
      optional port number), anything after is simply commentary.

  Translation Actions
      The following action procedures are registered for Xarchie and can  be
      bound  to  widget  events  using the translations resource (see the Xt
      manual, Appendix C). The actions of the browser widgets are hard-coded
      since they are so essential to correct behaviour.  They can however be
      bound to different events using the  notify()  action  (that  is,  you
      could  notify  on some other event than mouse clicks, if you know what
      you're doing).

   Main panel actions
      quit()
           Exit Xarchie.  By default this is  invoked  by  selecting  "Quit"
           from the File menu or by typing "Meta-Q" in any non-Text widget.

      query()
           Send the current  contents  of  the  "Search  Term"  text  widget
           (searchText)  to Archie.  By default this is performed by hitting
           Return in searchText or by selecting "Query Item" from the  Query
           menu.

      query-host()
           Fills the browser with the contents of the root directory of  the
           host  given by the contents of the "Host" text widget (hostText).
           By default this is performed by hitting Return in hostText or  by
           by selecting "Query Host" from the Query menu.

      query-location()
           Fills the browser with the contents of the directory given by the

           "Location"  text  widget (locationText) and the host given by the
           contents of the "Host" text widget (hostText).  By  default  this
           is  performed  by  hitting Return in locationText or by selecting
           "Query Location" from the Query menu.

      abort()
           Aborts the current query at the soonest  possible  time.  Has  no
           effect  is  a query is not currently being processed. By default,
           this invoked by clicking on the Abort button when it is active.

      query-or-abort()
           Invokes either query() or abort(), depending on whether  a  query
           is in progress.

      about()
           Pops up the About panel.

      ftp-get()
           Begin retrieval of the currently-selected files. By default  this
           is  invoked by selecting "Get" from the "File" menu, or by typing
           "Meta-G" in any non-Text widget.

   Browser actions
      Items are selected in the browser using  the  Left  mouse  button,  as
      usual.   Clicking with Shift does not clear other selections, allowing
      multiple selections.  This  is  implemented  using  the  XfwfMultiList
      translation  actions Notify(), Set(), Toggle(), and OpenMany(), unless
      your version of Xarchie was compiled  to  not  use  the  XfwfMultiList
      widget  (see  the  Imakefile or your local installer).  Modify at your
      own risk!

      The following actions are used for other browser operations.

      browser-up()
           Shifts  the  browser  left  (i.e.,  up  the  file  hierarchy)  if
           possible.   By  default  this is invoked by clicking on the "<<<"
           button (browserUpButton), or by clicking the Middle mouse  button
           in  the  browser,  or  by  hitting the "Left" key (often the left
           arrow on the cursor keypad).

      browser-down()
           Shifts the browser  right  (ie.,  down  the  file  hierarchy)  if
           possible.   By  default  this is invoked by clicking on the ">>>"
           button (browserDownButton), or by clicking the Right mouse button
           in  the  browser,  or by hitting the "Right" key (often the right
           arrow on the cursor keypad).

      browser-top()
           Shifts the browser to its leftmost position (i.e., the top of the
           file  hierarchy).   By  default  this is invoked by clicking with
           Shift on the "<<<" button (browserUpButton)  or  by  hitting  the

           "Home" key.

      browser-open-directories()
           Expands  selected  directories.  If  the  browser  was   expanded
           uniquely  and  successfully,  it will be shifted right to display
           the new information.  By default,  this  is  invoked  by  double-
           clicking in the browser.

      browser-open-files()
           Retrieves selected  files  by  FTP  into  a  temporary  file  and
           displays them using View windows.

      browser-open-all()
           Opens the selected items by expanding  selected  directories  and
           retrieving  selected  files  for  viewing.   By  default, this is
           invoked by selecting "Open" from the  File  menu,  or  by  typing
           "Meta-O" in any non-text widget.

   Settings actions
      The following actions control the Settings Panel and can  be  used  to
      change some settings without using the panel.

      popup-settings()
           Pops up the Settings  Panel,  and  resets  its  values  to  those
           currently  in  effect. Raises the Settings Panel if it is already
           popped up. By default this is performed by selecting  "Other"  on
           the Settings menu.

      settings-apply()
           Sets the current settings from the values on the Settings  Panel.
           By  default  this  is performed by clicking the "Apply" button on
           the Settings Panel.

      settings-default()
           Resets the values on the Settings Panel to the default  settings,
           but   does   not   affect   the   current   settings   until  the
           settings-apply() action is invoked. By default, this  is  invoked
           by clicking on the "Default" button on the Settings Panel.

      settings-done()
           Pops down the Settings Panel. If there are changes that have  not
           be  applied,  then a popup confirm box allows the user to discard
           the settings or go back and apply  them.   By  default,  this  is
           invoked by clicking on the "Done" button on the Settings Panel.

      set-host(hostname)
           This action sets the Archie host as  indicated  on  the  Settings
           Panel,  but  does  not  affect  the  current  settings  until the
           settings-apply() action is invoked.

      set-host-now(hostname)
           Sets  the   Archie   host   immediately   without   waiting   for
           settings-apply().

      set-search-type(type)
           This action sets the searchType  as  indicated  on  the  Settings
           Panel,  but  does  not  affect  the  current  settings  until the
           settings-apply() action is invoked.

      set-search-type-now(type)
           Sets   the   searchType   immediately   without    waiting    for
           settings-apply().

      set-sort-type(type)
           This action sets the sortType as indicated on the Settings Panel,
           but   does   not   affect   the   current   settings   until  the
           settings-apply() action is invoked.

      set-sort-type-now(type)
           Sets   the   sortType    immediately    without    waiting    for
           settings-apply().

      set-nice-level(level)
           This action sets the  niceLevel  as  indicated  on  the  Settings
           Panel,  but  does  not  affect  the  current  settings  until the
           settings-apply() action is invoked.

      set-nice-level-now(level)
           Sets   the   niceLevel   immediately    without    waiting    for
           settings-apply().

      settings-submenu()
           This action procedure is documented here only  for  completeness.
           It  should  only be used for BtnMotion events in the settingsMenu
           widget.  It  invokes  the  appropriate  pullright  menu  for  the
           Settings menu. Believe me, you don't want to deal with this.

   File actions
      The operation of the File panel is hard-coded. The  following  actions
      are used to pop it up however:

      file-save()
           Pops up the File panel, and resets its values in preparation  for
           saving  the  database.  By  default  this is invoked by selecting
           "Save" from the "File" menu or by typing "Meta-S" in any non-Text
           widget.

      file-load()
           Pops up the File panel, and resets its values in preparation  for
           reloading  the  database. By default this is invoked by selecting
           "Load" from the "File" menu or by typing "Meta-L" in any non-Text

           widget.

      file-write()
           Pops up the File panel, and resets its values in preparation  for
           writing the database in a human-readable form. By default this is
           invoked by selecting "Write" from the "File" menu  or  by  typing
           "Meta-W" in any non-Text widget.

   Help actions
      help()
           Pops up the Help panel.

      help-done()
           Dismisses the Help panel.

      help-prev()
      help-next()
           Selects the previous or next help topic, respectively.

      help-up()
      help-down()
           Scrolls the text of the current help topic up or down  one  page,
           respectively.   This is an alternative to using the Text widget's
           scrollbar.

   Miscellaneous actions
      ftp-trace-done()
           Dismisses the FTP Trace window. By default, this  is  invoked  by
           clicking on the "Dismiss" button in the FTP Trace window.

  Environment Variables
      The following environment variables are used by Xarchie  if  they  are
      defined:

      TMPDIR         - Directory for "Open"-ed files
      XAPPLRESDIR    - Directory containing Xarchie resource file
      USER           - Username for FTP mail address
      HOSTNAME       - Hostname for FTP mail address

  Files
      Xarchie        - default Xarchie resource file

  Diagnostics
      Xarchie indicates X errors using  the  ever-popular  default  X  error
      handler  that prints a message and dies, possibly leaving a large core
      dump somewhere.

      Errors due to incorrect resource specifications cause an error message
      on stderr, but do not kill Xarchie (usually).

      Errors due to incorrect user commands or problems with the  connection
      to Archie result in a popup alert box being displayed. Clicking on the
      indicated button in the alert box will make it go away and  allow  you
      to continue.

      An incorrect value for the FTP mail address (as  determined  from  the
      system information or from the USER and HOSTNAME variables) can result
      in access  being  denied  by  some  anonymous  FTP  servers.  See  the
      description  of  the ftpMailAddress non-widget resource if your system
      has problems with this.

      If you continually get "Can't resolve hostname" errors when you try to
      query,  then  Xarchie  was  not  built  properly.  Contact  your local
      maintainer and suggest that they read the PROBLEMS file concerning the
      "resolv" library.

      If your queries always time out, then  there  are  two  possibilities.
      First,  and by far the most likely, is that the server is simply busy.
      Try again later. The other possibility is that UDP traffic is disabled
      on  your system. You should contact your local maintainer and ask them
      to read the PROBLEMS files concerning UDP traffic.

  Known Bugs
      Crashes have been observed when the Help text is scrolled. There is no
      fix, but see the PROBLEMS file for some discussion.

      The list of files  in  the  FileChooser  widgets  don't  seem  to  get
      displayed  properly  all the time. That is, sometimes items seem to be
      drawn  on  top  of   each   other.   Refreshing   the   window   (eg.,
      iconify/deiconify  or scrolling up/down) clears it up. This seems like
      an Xaw bug, but is difficult to repeat in isolation.

      Your mileage may vary regarding the Xarchie icon changing  to  reflect
      search  and  transfer  status.  Your  window  manager  may not support
      application-specified  icons,  or  may  not  support   them   changing
      dynamically. See the PROBLEMS file for some discussion.

      It is not  currently  possible  to  abort  during  nameserver  lookup.
      Perhaps some day I'll get motivated to add asynchronous DNS code.

      The browser has a hard-coded maximum depth, beyond  which  you  cannot
      expand directories. I don't think it will be a major problem however.

  Reporting Bugs
      If you have problems with or  questions  about  an  individual  Archie
      server  site,  contact  archie-admin  at  that  site.  If you have any
      questions about Archie itself, write to info@bunyip.com. If  you  have
      questions  about  Prospero, write to info-prospero@isi.edu. The USENET
      newsgroup comp.archives.admin may also be helpful.
