 XRT
      xrt - Display a short text file in the root window


 SYNOPSIS
      xrt [-?] [-a] [-b colour] [-c] [-d] [-f font] [-g gap] [-h] [-
      l linewidth] [-n] [-p percentage] [-r] [-s colour] [-t title] [-
      w width] [filename [filename...]]

 DESCRIPTION
      xrt writes a box containing text directly onto the root window, with
      an optional title line. Its primary use is to display the motd on the
      xdm login screen (i.e. prior to the user logging in).

 OPTIONS
      The following options are recognised:

           -?   Display a syntax usage message.

           -a   Only display characters in the range ASCII 32 to 126. Tabs
                and linefeeds are the only other characters dealt with if
                this option is used.

           -b colour
                Sets the specified background colour for the box, the
                default being beige.

           -c   Centre the text in each line of the box. Leading and
                trailing spaces (after tab expansion) are removed prior to
                the centralisation of the text. This is particularly useful
                for proportional fonts.

           -d   Add the time and date (of the most recent file specified or
                the current time if standard input is used) at the top of
                the text box. TZ is used for the time zone, but a fallback
                time zone can be hard-coded in during compile-time for use
                when the TZ environmental variable isn't set (e.g. during
                the xdm login screen).

           -f font
                Use the font specified instead of the default 9x15 font
                (unless the specified font doesn't exist). Either
                proportional or non-proportional fonts can be used, although
                it is recommended that you use -c to centre proportional
                fonts.

           -g gap
                Add the specified number of pixels as an inter-line gap, the
                default being 1 pixel. Negative values can be specified if
                you want pointlessly overlapping lines of text.

 xrt(1)                                                               xrt(1)




           -h   Use a horizontal line to split each readable file (assuming
                there are 2 or more such files) that is displayed. This
                enforces a limit of 16 readable files. The line width
                specified via -l is ignored - the line is always one pixel
                high.

           -l linewidth
                Sets the line width of the box border (default is 3). A line
                width of 0 means no border around the box.

           -n   Add the last openable filename to the title at the top of
                the box (<stdin> is displayed if standard input is used).

           -p percent
                Specify the percentage down from the top of the screen where
                the vertical centre of the box (excluding the title) is
                located. Defaults to 50%. This is a percentage so that
                different sized screens will still have sensible
                positioning. For xdm login screens, the author recommends an
                80% setting.

           -r   Switch to reverse video (i.e. flip foreground and background
                colours).

           -s colour
                Sets the specified foreground colour for the text and
                borders, the default being navyblue.

           -t title
                Adds the specified title to the top of the box, overriding
                the -n option. It can still be combined with the -d option
                though.

           -w width
                Set a fixed width in pixels for the box (excluding any
                borders). This overrides the default behaviour, which is to
                dynamically calculate the box width based on the longest
                string to be displayed.

 CLEVER BITS
      xrt will not draw anything if no lines of text or only blank lines of
      text are supplied. It also converts tabs into spaces using a tabstop
      of 8 characters.  Files that can't be read are skipped with a warning
      to stderr. The box is now intelligently positioned/truncated on the
      screen, so it usually avoids being partially off the screen (-h might
      fool it though).

 BUGS
      Nothing at the moment, he says with a grin.
