+% gslp.ps - format and print text
+
+% This utility provides functionality approximately equivalent to the Unix
+% `enscript' program. It prints plain text files using a single font.
+% It currently handles tabs and formfeeds, but not backspaces.
+% It will line-wrap when using fixed-pitch fonts.
+% It will also do kerning and width adjustment.
+% Standard switches implemented:
+% -12BclqRr -b<header> -f<font> -F<hfont> -L<lines> -p<outfile>
+% Sun switches implemented:
+% -T<n> set tab width
+% Switches ignored:
+% -GghKkmow -# -C -d -J -n -P -S -s -t -v
+% Switches added:
+% --add-to-space <units>
+% add the given number of 1/72" units to the width of each
+% space (may be negative)
+% --add-to-width <units>
+% add the given number of 1/72" units to the width of each
+% character (may be negative)
+% --columns <n>
+% print in <n> columns
+% --detect
+% treat the file as PostScript if it starts with %!
+% --first-page <n>
+% start printing at page <n>
+% --kern <file.afm>
+% kern using information from the given .AFM file
+% --last-page <n>
+% stop printing after page <n>
+% --(heading|footing)-(left|center|right) <string>
+% set the heading/footing fields; use -B first to clear
+% --margin-(top|bottom|left|right) <inches>
+% set a margin
+% --no-eject-(file|formfeed)
+% end-of-file/FF only starts a new column, not a new sheet
+% --spacing <n>
+% use double (n=2), triple (n=3), etc. spacing
+% Also, the string %# in a heading or footing is replaced with the page #.
