+usage="\
+Usage: $program [OPTIONS] FILE
+Try to fix common PostScript problems that break postprocessing.
+
+Options:
+ -h, --help              display this help and exit
+ -v, --version           display version information and exit
+ -q, --quiet             don't print informational messages
+ -o, --output=FILE       save result in FILE.  If FILE is \`-', send to stdout
+ -f, --force             force full rewrite by ghostscript
+ -n, --no-fix            don't fix the FILE, but still honor \`-o'
+ -c, --check, --dry-run  don't perform any action
+
+Fixes:
+ - Remove junk before and after PostScript content
+ - Use only Unix end of lines (\\n)
+ - Remove empty lines
+ - Fix Apple prologue (fixmacps)
+ - Fix FrameMaker prologue (fixfmps)
+ - Fix CorelDraw prologue (fixnt)
+ - Fix Windows NT 3.5/4.0 prologue (fixnt)
+ - Fix Windows 95 prologue
+ - Ensure there is a \`%%BeginSetup/%%EndSetup' section
+ - Removes Canvas' extraneaous \`%%EndDocument:' comments
+ - Split too long lines
+
+If the FILE seems really in a bad state, ghostscript may be used to perform
+a full rewrite.  The output might then be significantly bigger, but much
+safer.

+usage=["\
+Usage: $program [OPTIONS] FILE
+Try to fix common PostScript problems that break postprocessing.
+
+Options:
+ -h, --help              display this help and exit
+ -v, --version           display version information and exit
+ -q, --quiet             don't print informational messages
+ -o, --output=FILE       save result in FILE.  If FILE is \`-', send to stdout
+ -f, --force             force full rewrite by ghostscript
+ -n, --no-fix            don't fix the FILE, but still honor \`-o'
+ -c, --check, --dry-run  don't perform any action
+
+Fixes:
+ - Remove junk before and after PostScript content
+ - Use only Unix end of lines (\\n)
+ - Remove empty lines
+ - Fix Apple prologue (fixmacps)
+ - Fix FrameMaker prologue (fixfmps)
+ - Fix CorelDraw prologue (fixnt)
+ - Fix Windows NT 3.5/4.0 prologue (fixnt)
+ - Fix Windows 95 prologue
+ - Ensure there is a \`%%BeginSetup/%%EndSetup' section
+ - Removes Canvas' extraneaous \`%%EndDocument:' comments
+ - Split too long lines
+
+If the FILE seems really in a bad state, ghostscript may be used to perform
+a full rewrite.  The output might then be significantly bigger, but much
+safer.

+ -q, --quiet          don't print informational messages
+ -o, --output=FILE    save result in FILE.  If FILE is \`-', send to stdout
+ -n, --no-fix         don't run \`fixps' to fix PS problems in FILE
+changequote(, )dnl
+ -S, --setpagedevice=KEY[:VALUE]  pass a page device definition to output.
+changequote([, ])dnl
+                      Multiple values accumulate
+ -a, --at=PAGE        insert the page device definitions at PAGE.  Default
+                      is PAGE=0, standing for the Document's Setup section
+

+usage="Usage: $program [OPTION]... FILE...
+
+Run each Texinfo or LaTeX FILE through TeX in turn until all
+cross-references are resolved, building all indices.  The directory
+containing each FILE is searched for included files.  The suffix of FILE
+is used to determine its language (LaTeX or Texinfo).
+
+Makeinfo is used to perform Texinfo macro expansion before running TeX
+when needed.
+
+Operation modes:
+  -b, --batch         no interaction
+  -c, --clean         remove all auxiliary files
+  -D, --debug         turn on shell debugging (set -x)
+  -h, --help          display this help and exit successfully
+  -o, --output=OFILE  leave output in OFILE (implies --clean);
+                      Only one input FILE may be specified in this case
+  -q, --quiet         no output unless errors (implies --batch)
+  -s, --silent        same as --quiet
+  -v, --version       display version information and exit successfully
+  -V, --verbose       report on what is done
+
+TeX tuning:
+  -@                   use @input instead of \input; for preloaded Texinfo
+  -e, --expand         force macro expansion using makeinfo
+  -I DIR               search DIR for Texinfo files
+  -l, --language=LANG  specify the LANG of FILE (LaTeX or Texinfo)
+  -p, --pdf            use pdftex or pdflatex for processing
+  -t, --texinfo=CMD    insert CMD after @setfilename in copy of input file
+                       multiple values accumulate
+
+The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
+TEX (or PDFTEX), and TEXINDEX environment variables are used to run
+those commands, if they are set.
