+=head1 NAME
+
+a2ping.pl -- convert between PS, EPS and PDF and other page description
+formats
+
+=head1 SYNOPSIS
+
+Z<> B<a2ping.pl> [B<-->]B<help>
+ B<a2ping.pl> [B<-->]B<doc>
+ B<a2ping.pl> [I<options>] <I<inputfile>> [[I<outformat>:] I<outputfile>]
+
+=head1 DESCRIPTION
+
+B<a2ping> is a UNIX command line utility written in Perl that
+converts many raster image and vector graphics formats to EPS or PDF and
+other page description formats. Accepted input file formats are: PS
+(PostScript), EPS, PDF, PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX,
+TGA. Accepted output formats are: EPS, PCL5, PDF, PDF1, PBM, PGM, PPM,
+PS, markedEPS, markedPS, PNG, XWD, BMP, TIFF, JPEG, GIF, XPM.
+B<a2ping> delegates the low-level work to
+Ghostscript (GS), B<pdftops> and B<sam2p>. B<a2ping> fixes many glitches
+during the EPS to EPS conversion, so its output is often more compatible
+and better embeddable than its input.
+
+Without the C<--below> option, it is guarenteed to start at the 0,0
+coordinate. C<--below>, C<--hires> and C<-v> are recommended options.
+
+The page size is set exactly corresponding to the BoundingBox.
+This means that when Ghostscript renders it, the result needs no
+cropping, and the PDF MediaBox is correct.
+
+If the bounding box is not right, of course, you have problems. If you
+feed crap in, you get crap. But you can supply the
+B<--bboxfrom=compute-gs> option to make GS recompute the bounding box.
+
+The name of the input file doesn't matter -- B<a2ping> detects the file
+format based on the first few bytes of the file. The name of the output
+file matters if I<outformat> is missing from the command line: then the
+extension of the output file determines the FileFormat (I<outformat>).
+
+=head1 EXTERNAL PROGRAMS
+
+The internal file format of B<a2ping.pl> is PS/EPS. Everything read is
+first converted to PS or EPS, then processed by B<a2ping.pl>, then
+converted to the output format.
+
+To analyse the bounding box and other properties of non-EPS PS files
+(and EPS files with option B<--bboxfrom> other than B<=guess>), GS is
+used. Converting PS to EPS involves this analysis.
+
+To write PDF files, GS is used.
+
+To read PDF files, B<pdftops> from the B<xpdf> package is used.
+
+Sampled input formats are PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX
+and TGA. To read sampled input formats, B<sam2p> is used. B<sam2p> is
+a raster image converter written in C++ by the author of B<a2ping.pl>.
+
+Extra output formats are PNG, XWD, BMP, TIFF, JPEG, GIF and XPM. To
+write extra output formats, B<sam2p> and GS are used.
+
+PNM output formats are PGM, PGM and PPM. To write PNM output formats, GS
+is used.
+
+
+=head1 TIPS AND TRICKS
+
+=over 2
+
+=item *
+
+Call with the B<-v> option to see progress and debug messages.
+
+=item *
+
+If your EPS contains a wrong bounding box, you can fix it by running
+C<a2ping.pl -v --bboxfrom=compute-gs thefile.eps -->
+
+=item *
+
+You can specify B<-> as I<inputfile> to get stdin and as I<outputfile>
+to get stdout. This works even for PDF files (which must be seekable),
+because B<a2ping> copies them to a temporary file automatically.
+
+=item *
+
+If I<inputfile> and I<outputfile> are the same, B<a2ping> copies the
+I<inputfile> to a temporary location first. However, this usage is
+recommended only if there is a backup of the file to be restored in case
+B<a2ping> doesn't produce the desired result.
+
+=item *
+
+If you specify B<--> as I<outputfile>, it will be the same as I<inputfile>.
+
+=item *
+
+B<a2ping> respects B<--Duplex> for FileFormat PCL5, even though GS doesn't.
+
+=item *
+
+If you have an incompatible PS that GS can read but your printer cannot print,
+just run C<a2ping.pl foo.ps PDF: - | a2ping.pl - PS: foo.ps>
+
+=item *
+
+If you have a PS coming from Win32 (often with extension C<.prn>), run
+it through B<a2ping>. It will remove the resolution changes and the
+progress text printed to the terminal (which confuses gv(1) and makes
+some filters in the print queue emit incorrect output).
+
+=item *
+
+B<a2ping> does antialiasing (B<--antialias=scale3no>) of glyphs and
+curves when emitting a sampled image (FileFormats such as PGM and PPM).
+This improves readability of the glyphs. B<=yes> instructs GS to do
+internal antialiasing, but it usually doesn't improve much. B<=scale3no>
+turns off GS internal antialiasing, but makes it render everything 3x3
+as big, and then scales it back down. B<=scale3no> turns on both 3x3
+scaling and GS internal antialiasing, which results in thicker lines and
+worse quality in general.
+
+=item *
+
+When creating a PBM file, antialiasing usually doesn't improve the
+quality, so it is switched off by default. But if you set
+B<--antialias=scale3no> or B<--antialias=scale3yes>, GS will render a PGM file,
+and the value of B<--threshold> determines the minimum intensity for white in
+the final PBM.
+
+=item *
+
+If you need a bigger sampled output file, specify a larger
+B<--Resolution>. The default is B<--Resolution=72>. If your sampled output file
+is going to be really big, you should specify B<--AntiAlias=yes> instead of
+the default B<--AntiAlias=scale3no> to speed up conversion.

+=head1 AUTHORS
+
+The author of B<a2ping> is Szab� P�ter <F<pts@fazekas.hu>>.
+
+B<a2ping> is inspired by and historically based on the B<epstopdf> Perl
+script modified by Thomas Esser, Sept. 1998, but his modifications have
+been removed from B<a2ping>, and also B<a2ping> and B<epstopdf> do not
+share common code anymore.  B<epstopdf> is written by Sebastian Rahtz,
+for Elsevier Science. B<epstopdf> contained extra tricks from Hans Hagen's
+texutil.

+Usage: dvired [options] file
+
+This programm behaves like dvips, execpt fot the fact that two logical
+pages will be put on onto each physical sheet of paper.
+
+For options see dvips(1). This program only interprets the options
+-o, -P and -f. All other options will directly be passed to dvips.
+
+If your paper is not in A4 format, you need to adjust the dimensions
+in this program.
+
+Examples: (it is assumed that the PRINTER-variable is set)
+   dvired -Plw foo                 send output to printer lw
+   dvired -o foo.ps foo            send output to file foo.ps
+   dvired -pp4-7 foo               send 4 output-pages to printer
+   dvired foo -f | ghostview -     preview output with ghostview

+# 1) cannot handle \input{fname} split over more than one line.
+#    1.5) cannot handle multiple \input{} or \includegraphics{} on one line.

+#	   -- given by \DeclareGraphicsExtensions{}?)

+
+# A script to transform an EPS file so that:
+#   a) it is guarenteed to start at the 0,0 coordinate
+#   b) it sets a page size exactly corresponding to the BoundingBox
+# This means that when Ghostscript renders it, the result needs no
+# cropping, and the PDF MediaBox is correct.
+#   c) the result is piped to Ghostscript and a PDF version written
+#
+# It needs a Level 2 PS interpreter.
+# If the bounding box is not right, of course, you have problems...
+#
+# The only thing I have not allowed for is the case of
+# "%%BoundingBox: (atend)", which is more complicated.

+#
+# History
+#  1999/05/06 v2.5 (Heiko Oberdiek)
+#    * New options: --hires, --exact, --filter, --help.
+#    * Many cosmetics: title, usage, ...
+#    * New code for debug, warning, error
+#    * Detecting of cygwin perl
+#    * Scanning for %%{Hires,Exact,}BoundingBox.
+#    * Scanning only the header in order not to get a wrong
+#      BoundingBox of an included file.
+#    * (atend) supported.
+#    * uses strict; (earlier error detecting).
+#    * changed first comment from '%!PS' to '%!';
+#    * corrected (atend) pattern: '\s*\(atend\)'
+#    * using of $bbxpat in all BoundingBox cases,
+#      correct the first white space to '...Box:\s*$bb...'
+#    * corrected first line (one line instead of two before 'if 0;';
+#  2000/11/05 v2.6 (Heiko Oberdiek)
+#    * %%HiresBoundingBox corrected to %%HiResBoundingBox
+#  2001/03/05 v2.7 (Heiko Oberdiek)
+#    * Newline before grestore for the case that there is no
+#      whitespace at the end of the eps file.
+#  2002/02/18 v2.8draft (Gerben Wierda)
+#    * Handle different eol styles transparantly
+#    * Applied fix from Peder Axensten for Freehand bug
+#  2002/02/21 v2.8draft (Gerben Wierda)
+#    * Fixed bug where last line of buffer was not copied out (ugh!)
+#  2003/04/22 v2.9draft (Gerben Wierda)
+#    * Fixed bug where with cr-eol files everything up to the first %!
+#    * in the first 2048 bytes was gobbled (double ugh!)
+#  2004/03/17 v2.9.1draft (Gerben Wierda)
+#    * No autorotate page
+#  2005/09/29 v2.9.2draft (Gerben Wierda)
+#    * Quote OutFilename
+#  2005/10/01 v2.9.3draft (Gerben Wierda)
+#    * Quote OutFilename
+#  2005/10/06 v2.9.4gw (Gerben Wierda)
+#    * This has become the official version for now
+#  2005/10/06 v2.9.5gw (Gerben Wierda)
+#    * Fixed a horrendous bug in the (atend) handling code

+=head1 NAME
+
+perltex - enable LaTeX macros to be defined in terms of Perl code
+
+=head1 SYNOPSIS
+
+perltex
+[B<--help>]
+[B<--latex>=I<program>]
+[B<-->[B<no>]B<safe>]
+[B<--permit>=I<feature>]
+[B<--makesty>]
+[I<latex options>]
+
+=head1 DESCRIPTION
+
+LaTeX -- through the underlying TeX typesetting system -- produces
+beautifully typeset documents but has a macro language that is
+difficult to program.  In particular, support for complex string
+manipulation is largely lacking.  Perl is a popular general-purpose
+programming language whose forte is string manipulation.  However, it
+has no typesetting capabilities whatsoever.
+
+Clearly, Perl's programmability could complement LaTeX's typesetting
+strengths.  B<perltex> is the tool that enables a symbiosis between
+the two systems.  All a user needs to do is compile a LaTeX document
+using B<perltex> instead of B<latex>.  (B<perltex> is actually a
+wrapper for B<latex>, so no B<latex> functionality is lost.)  If the
+document includes a C<\usepackage{perltex}> in its preamble, then
+C<\perlnewcommand> and C<\perlrenewcommand> macros will be made
+available.  These behave just like LaTeX's C<\newcommand> and
+C<\renewcommand> except that the macro body contains Perl code instead
+of LaTeX code.
+
+=head1 OPTIONS
+
+B<perltex> accepts the following command-line options:
+
+=over 4
+
+=item B<--help>
+
+Display basic usage information.
+
+=item B<--latex>=I<program>
+
+Specify a program to use instead of B<latex>.  For example,
+C<--latex=pdflatex> would typeset the given document using
+B<pdflatex> instead of ordinary B<latex>.
+
+=item B<-->[B<no>]B<safe>
+
+Enable or disable sandboxing.  With the default of B<--safe>,
+B<perltex> executes the code from a C<\perlnewcommand> or
+C<\perlrenewcommand> macro within a protected environment that
+prohibits ``unsafe'' operations such as accessing files or executing
+external programs.  Specifying B<--nosafe> gives the LaTeX document
+I<carte blanche> to execute any arbitrary Perl code, including that
+which can harm the user's files.  See L<Safe> for more information.
+
+=item B<--permit>=I<feature>
+
+Permit particular Perl operations to be performed.  The B<--permit>
+option, which can be specified more than once on the command line,
+enables finer-grained control over the B<perltex> sandbox.  See
+L<Opcode> for more information.
+
+=item B<--makesty>
+
+Generate a LaTeX style file called F<noperltex.sty>.  Replacing the
+document's C<\usepackage{perltex}> line with C<\usepackage{noperltex}>
+produces the same output but does not require PerlTeX, making the
+document suitable for distribution to people who do not have PerlTeX
+installed.  The disadvantage is that F<noperltex.sty> is specific to
+the document that produced it.  Any changes to the document's PerlTeX
+macro definitions or macro invocations necessitates rerunning
+B<perltex> with the B<--makesty> option.
+
+=back
+
+These options are then followed by whatever options are normally
+passed to B<latex> (or whatever program was specified with
+C<--latex>), including, for instance, the name of the F<.tex> file to
+compile.
+
+=head1 EXAMPLES
+
+In its simplest form, B<perltex> is run just like B<latex>:
+
+    perltex myfile.tex
+
+To use B<pdflatex> instead of regular B<latex>, use the B<--latex>
+option:
+
+    perltex --latex=pdflatex myfile.tex
+
+If LaTeX gives a ``C<trapped by operation mask>'' error and you trust
+the F<.tex> file you're trying to compile not to execute malicious
+Perl code (e.g., because you wrote it yourself), you can disable
+B<perltex>'s safety mechansisms with B<--nosafe>:
+
+    perltex --nosafe myfile.tex
+
+The following command gives documents only B<perltex>'s default
+permissions (C<:browse>) plus the ability to open files and invoke the
+C<time> command:
+
+    perltex --permit=:browse --permit=:filesys_open
+      --permit=time myfile.tex
+
+=head1 ENVIRONMENT
+
+B<perltex> honors the following environment variables:
+
+=over 4
+
+=item PERLTEX
+
+Specify the filename of the LaTeX compiler.  The LaTeX compiler
+defaults to ``C<latex>''.  The C<PERLTEX> environment variable
+overrides this default, and the B<--latex> command-line option (see
+L</OPTIONS>) overrides that.
+
+=back
+
+=head1 FILES
+
+While compiling F<jobname.tex>, B<perltex> makes use of the following
+files:
+
+=over 4
+
+=item F<jobname.lgpl>
+
+log file written by Perl; helpful for debugging Perl macros
+
+=item F<jobname.topl>
+
+information sent from LaTeX to Perl
+
+=item F<jobname.frpl>
+
+information sent from Perl to LaTeX
+
+=item F<jobname.tfpl>
+
+``flag'' file whose existence indicates that F<jobname.topl> contains
+valid data
+
+=item F<jobname.ffpl>
+
+``flag'' file whose existence indicates that F<jobname.frpl> contains
+valid data
+
+=item F<jobname.dfpl>
+
+``flag'' file whose existence indicates that F<jobname.ffpl> has been
+deleted
+
+=item F<noperltex-#.tex>
+
+file generated by F<noperltex.sty> for each PerlTeX macro invocation
+
+=back
+
+=head1 NOTES
+
+B<perltex>'s sandbox defaults to what L<Opcode> calls ``C<:browse>''.

+# Reqirements: Perl5, dvips
+# History:
+#   2001/04/12 v0.1:
+#     * First try.
+#   2001/04/13 v0.2:
+#     * TeX/dvips is called for each font for the case of errors.
+#     * First release.
+#   2001/04/15 v0.3:
+#     * Call of kpsewhich with option --progname.
+#     * Extracting of texps.pro from temporary PostScript file,
+#       if kpsewhich failed.
+#     * Option -G0 for dvips run added.
+#   2001/04/16 v0.4:
+#     * Support for merging PostScript fonts added.
+#     * \special{!...}/@fedspecial detection added.
+#     * Bug fix: I detection.
+#   2001/04/17 v0.5:
+#     * Redirection of stderr (dvips run) if possible.
+#   2001/04/20 v0.6:
+#     * Bug fix: dvips font names can contain numbers.
+#   2001/04/21 v0.7:
+#     * Bug fix: long dvi file name in ps file.
+#   2001/04/23 v0.8:
+#     * Bug fix: post string parsing.
+#   2001/04/26 v0.9:
+#     * Check of version number of dvips in PostScript file.
+#   2001/06/30 v1.0:
+#     * Problem with DOS line endings fixed.
+#   2005/01/28 v1.1:
+#     * Bug fix: encoding files are now included also.
+#     * The intermediate DVI files are written directly.
+#     * LPPL 1.3
+#   2005/01/29 v1.2:
+#     * Merging is now based on type 1 names. This solves
+#       the problem, if different bitmap fonts maps to the
+#       same type 1 font, eg. (ecrm1000, larm1000) -> SFRM1000.
+#     * Suppression of PK generation, if environment variable
+#       MKTEXPK is supported.
+#     * If output file is "-" (standard output) then messages of
+#       pkfix are written to standard error output.
+#   2005/02/25 v1.3:
+#     * Bug fix: Detection of "@fedspecial end" improved.
+#     * Bug fix: Typo corrected (PRT -> $PRT).

+
+# This script assumes that there is a config.pdf somewhere that sets
+# the bitmap mode to something large but realistic (real mode) so that
+# unavailable pfb fonts will be included as bitmaps.
+
+# Version 1.0:	added the string above for identification purposes
+# Version 1.0a:	Cosmetic change: do not display dir of argv[0] all the time
+#		Added calledas variable to hold command basename
+# Version 1.1:	Use calledas instead of $0 which means the sed command
+#		for determining format below also works when there is no dir
+#		(run from dir where altpdftex resides, not very likely...)
+# Version 1.2:	Force the use of tex binaries from the same directory as
+#		this script
+# Version 1.3:  Added --echo-version option, placed argument check after
+#		switch, inside while to prevent subscript out of range error
+#		Added --tex-path to override directory where this script
+#		resides. Added --gs-path to override a new default gs
+#		directory /usr/local/bin. Also, force gs directory at the
+#		start of the path to repair for broken installations of
+#		TeX, gs and such
+# Version 1.4:	Moved path changes to just before calling gs so that only
+#		ps2pdf is affected
+# Version 1.5:	Removed some path-related redundancy from GS calling
+# Version 1.5a:	Missing ${extradviopts} from echo
+#		Added version to --help output
+#		Added wolfram.map
+# Version 1.6:	Fixed bug: --dviopts did not work because it did set
+#		the wrong variable
+#		Changed dviopts to dvipsopts (better name)
+# Version 1.7:	Added --distiller and --distiller-filter option
+#		Changed --gs-path to --distiller-path
+#		Changed distiller semantics
+#		Fixed bug --tex-path flag needed trailing '/'
+#		Some extra quoting to be more robust for whitespace
+#		in names, also internally
+# Version 1.8:	Added pstill and u-psbuild info to help
+# Version 1.9:	Removed textrace bbold font (textrace is broken)
+# Version 1.10:	Added amstex support
+#		Simplified different format support
+# Version 1.11:	Do not source ~/.{t}cshrc, use the environment 'as is'
+#		Version 1.11 says it is version 1.10!
+# Version 1.12: Added textrace bold font (textrace 0.48 is ok)
+# Version 1.13:	Changed success message at the end
+#		Echo version on by default
+#		Debug option
+# Version 1.13b:Date report on version was very out of date, removed
+
+# Version 2.0:	Rewritten in /bin/sh because (t)csh does not handle signals
+#		very well...
+#		This version works, but you need to send the SIGTERM to
+#		the process group (the negative PID) to get it to work
+# Version 2.1:	Small bug fixes
+# Version 2.2:	Fixed bug where argument without extension was interpreted
+#		as dvi file.
+#		Removed dependencies on smart sh versions
+# Version 2.3:	Removed map file knowledge (needs to be outside this script)
+#		beyond the standard map files
+# Version 2.4:	Added support for omega and lambda (use odvips)
+# Version 2.5:	Changed maxpk and maxpfb implementation to recent updmap
+# Version 2.6:	Use ps2pdf13 as the default distiller
+# Version 2.7:	Changed help
+# Version 2.8:	Checked into CVS.
+#		Added handling of outdir for TeX
+# Version 2.9:	Added auto-outdir flag
+# Version 2.10:	Changed --outdir behaviour to mimick TEXMFOUTPUT,
+#		removed --auto-outdir
+# Version 2.11:	Fixed typo
+# Version 2.12:	RCS changes, from now on, the version number is the RCS number
+#		These notes here will become a ChangeLog.
+# 2003/05/20	Joachim's modification: write first to a pdf file in tmp, 
+#		and only upon completion copy the file to its final
+#		destination.  This is done in order to minimise the time where
+#		the pdf file in current directory is in an unstable state,
+#		because a PDF viewer might be tracking the file, and 
+#		if it finds the pdf file in an intermediate state it will
+#		display a blank page until the new version is ready.
+# 2003/05/21	Joachim's modification used /bin/cp. Gerben made it truly
+#		atomic by using /bin/cp in combination with /bin/mv
+# 2003/11/23	Added supportfor passing flasg to tex at the request of
+#		Dick Koch.
+# 2004/09/05	Bugfix: make it work better with directories with whitespace
+#		in their name
+# 2004/11/15	New calling mode: simpdftex format foo.tex
+#		e.g.:
+#			simpdftex latex foo.tex
+#		In the future, the old modes (altpdflatex and friends) through
+#		symlinks will disappear from my distribution, though they will
+#		still work.
+
+# FEATURE: it seems -u +foo.map -u -foo.map does not work. So --extradvipsopts
+# cannot be used to remove a map from the standard list
+
+# BUG: Handling of file name extensions is not completely equialent to TeX
+# i.e. foo.bar.bla gets you foo.bar.pdf not foo.bar.bla.pdf
+# Give all extensions

+
+simpdftex is a way to do pdf{e}{la}tex without having pdf{e}{la}tex. It needs a
+working TeX environment and ghostscript. Since pdf{e}{la}tex cannot handle
+insertion of .eps graphics, simpdftex gives an alternative. The output for both
+systems is comparable.
+
+simpdftex compiles the file with {LA}TeX, processes the DVI file with dvips into
+PostScript and uses gs to produce pdf (with ps2pdf). There is finegrained
+control over the resulting filename and the options with which dvips produces
+the PostScript intermediary file.
+
+Dvips will call Metafont to produce bitmaps or include PostScript .pfb files
+depending on the flags. See below.
+
+Default settings is normal name, maximal use of pfb's, just like pdf{la}tex,
+in other words, "pdftex file.tex" and "altpdftex file.tex" both produce an
+output file file.pdf. For pdftex, output options are controlled by pdftex.cfg,
+for altpdftext by config.ps (unless --pdf is given).
+
+Arguments:
+	tex-or-dvi-file
+		If a .dvi file is given, skip the TeX process. Otherwise, TeX
+		the input file, dvips the resulting dvi file and ps2pdf the
+		resulting ps file
+	--help
+		Display this message and exit
+	--no-echo-version
+		Do not echo location and version of this script. Does not exit
+		so can be used tochange info to the output of a real run
+	--debug
+		Add some debug output
+	--extendedname
+		Depending on the mode, adds intermediary extensions to the
+		output filename. If the mode is --pdf, .pdfmode is added. If
+		the mode is --maxpk, ,maxpk is added and if the mode is
+		--maxpfb, .maxpfb is added. Example:
+			tex-or-dvi-file-basename.maxpfb.pdf
+	--maxpk
+		Use Metafont bitmaps (pk files) when possible. Only real
+		PostScript fonts (like Times Roman) are included as
+		PostScript fonts. All other fonts are included as bitmaps
+		for the default printer resolution. This options produces
+		optimal results for the chosen printer.
+		For file contents (not name) equivalent to:
+		--dvipsopts "-Ppk"
+	--maxpfb
+		Use PostScript pfb files whenever possible. This produces
+		optimal results for the screen.
+		For file contents (not name) equivalent to:
+		--dvipsopts "-Poutline"
+		If any font is included as TeX pk bitmap, it is rendered
+		at the default resolution.
+	--pdf
+		Select .pdfmode extension for the output file name if
+		--extendedname has been set. Use printer definition
+		config.pdf. For file contents (not name) equivalent to
+		--dvipsopts "-Ppdf"
+		Note that the default config.pdf assumes resolution 8000
+		for bitmaps and bitmap generation fails at this resolution
+		because there exists no known mode for that resolution.
+	--default
+		Select no extension for the output file name, even if
+		--extendedfilename has been set. Use standard printer
+		definition config.ps. For file contents (not name) equivalent
+		to:
+		--dvipsopts "" --noextendedname
+	--dvipsopts
+		Give arbitrary arguments to dvips, e.g.
+		--dvipsopts "-M"
+		Sets extension for --extendedfilename to .custom. --dvipsopts
+		overrides other flags that set dvipsopts.
+	--extratexopts
+		Give extra arbitrary arguments to tex, e.g.
+		--extratexopts "--interaction=nonstopmode"
+		Sets extra options for the tex command that is used.
+	--extradvipsopts
+		Give extra arbitrary arguments to dvips, e.g.
+		--extradvipsopts "-M"
+		Sets extra options for dvips and does not set extension
+		or override other options. Options will be added to the end
+		of the options for dvips
+	--keep-psfile
+		After running dvips, copy the ps file over to the directory
+		where the tex file is, possibly overwriting a ps file
+		that is there. Use with caution, a ps file could be input
+		as well.
+	--tex-path
+		Give path of TeX binaries, use directory of this script
+		otherwise
+	--distiller prog
+		Use a distiller different from ps2pdf which is the default.
+		Argument must be an executable or executable script that
+		gets called iwth two arguments: input file (PS) and output
+		file (PDF). E.g.:
+		--distiller=/usr/local/alternate/bin/ps2pdf
+		--distiller=pstill
+		Using this flag sets the distiller filter mode to off
+	--distiller-filter prog
+		Use a distiller executable or executable script which is
+		called with the PS input as standard input and which writes
+		the PDF output to standard output. E.g.:
+		--distiller-filter=u-psbuild
+	--distiller-path
+		Give path needed by the distiller binary. This path is added
+		to the begin of you PATH environment before the distiller is
+		run. The reason is that for instance ps2pdf uses the path to
+		find gs and sets the path to something with /sw/bin at the
+		beginning.  Thus, installing gs from fink would make
+		/usr/local/bin/ps2pdf find another gs than intended. By giving
+		an empty path, the path is not changed before the distiller
+		program is run. The default is empty.
+	--outdir dir
+		Write files here *if* our current directory is unwritable. This
+		mimicks the TEXMFOUTPUT environment variable of TeX, but
+		differently. The current dir becomes the value of --outdir and
+		the directory where the old current dir is added to TEXINPUTS.
+		This is more robust for reading and locating files.
+		You can also set TEXMFOUTPUT instead, but with a disadvantage:
+		you will be running TeXin the current dir. And you will not be
+		able to read files in the outdir unless you also adapt
+		TEXINPUTS.
+
+	The defaults for the distiller are
+		Path addition: "${distillerpath}"
+		Filter mode: "${distillerfilter}"
+		Program: "${distillerprog}"
+
+	Later flags override settings of earlier flags.

+__END__
+Many TeX programmers provide more or less detailed manuals for
+their programs or packages. They are usually available as .dvi,
+.ps, .pdf, .html or plain text files (sometimes included in the
+.sty files instead of a separate documentation file) and can be
+accessed with this browser, which is simply an interface to find a
+documentation more easily. It starts the respective viewer for
+reading the selected documentation making use of a database file
+which contains the path entries according to the current teTeX
+texmf/doc structure; additional usage of a system-wide local and
+of individual user texmf trees with corresponding databases is also
+possible.
+The documentations are grouped in several categories shown in the
+main window; pressing one of its buttons lists all documentations
+belonging to this topic.
+The topic window lets you select one documentation file, view or
+send it to the default printer. By right-clicking on the selected
+item you get the complete path of the file.
+The search button of the main window allows you to search the
+database for a string; it does not search file names. Enter the
+string and hit <Return> to start the search or <Control-c> to
+cancel. Just hitting <Return> without typing something in will
+show the full list of files in the database.
+Defaults for the documentation root directory, the viewers, the
+converters, certain options and the printer are set in the global
+configuration file $sysrc.
+However, each user can put a copy of it as .texdocrc into his home
+directory to modify them according to his needs; modification or
+generation of ~/.texdocrc can also be done with the Settings menu.
+Additionally, the settings can be changed temporarily with this
+menu.
+
+The following key shortcuts are defined for use with the browser:
+  <Ctrl-q>	Quit browser
+  <Ctrl-m>	Raise the Main window to the foreground
+  <Ctrl-s>	Search a keyword in database (case insensitive)
+  <Ctrl-c>	Cancel/close subwindow or search entry widget
+  <Ctrl-v>	View selected document (topic windows)
+  <Ctrl-p>	Print selected document (topic windows)
+  <Ctrl-t>	Open settings menu
+  <Ctrl-k>	Kill fatal error message window (same as
+		<Ctrl-q>)
+  <Ctrl-h>	Open this help
+  <Return>	Equivalent to button press;
+		OK in selection menu and search
+  <Tab>		Next/previous widget
+
+There are the following command line options:
+  -a		autostart viewer if a listbox of search results
+		contains only one item; can also be set in a
+		configuration file
+  -v		disable suppression of viewer messages sent to
+		stderr and of certain permanent message popup
+		windows, in case this was not set in a
+		configuration file; default: off
+
+Some more information is available in the manpage of texdoctk.

+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, -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
+  -r, --recode         call recode before TeX to translate input characters
+  -t, --command=CMD    insert CMD in copy of input file
+   or --texinfo=CMD    multiple values accumulate
+
+The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
+TEX (or PDFTEX), TEXINDEX, and THUMBPDF environment variables are used
+to run those commands, if they are set.  Any CMD strings are added
+after @setfilename for Texinfo input, in the first line for LaTeX input.

+# Control of formatting:

+#     function along with the change in hash, if the change is the use
+#     of another function (in style_map).
+# 2.) For other changes, reimplement one of the t2h_default_<fnc>* routines,
+#     give them another name, and assign them to the respective
+#     $<fnc> variable (below).

+#   1999/02/14 v1.0: First release.
+#   1999/02/23 v1.1:
+#    * Looking for the media box to calculate the resolution
+#      for Ghostscript
+#    * new option --resolution
+#   1999/03/01 v1.2:
+#    * optimization: indirect objects for length values removed.
+#    * "first line" from epstopdf
+#   1999/03/12 v1.3:
+#    * Copyright: LPPL
+#   1999/05/05 v1.4:
+#    * Detecting of cygwin32 environment.
+#    * Minor corrections of output of error messages.
+#    * Sharing RGB objects.
+#   1999/06/13 v1.5:
+#    * gs detection extended.
+#   1999/07/27 v1.6
+#   1999/08/08 v1.7:
+#    * \immediate before \pdfobj (pdfTeX 0.14a)
+#   1999/09/09 v1.8
+#   1999/09/06 v1.9:
+#    * Check for direct /Length values (for jpg images)
+#   2000/01/11 v1.10:
+#    * Bug fix: /Length (direct) as last entry.
+#    * Direct /Length in RGB objects supported.
+#   2000/01/19 v1.11:
+#    * "for (my $j=0;...;...)"  replaced by "my $j; for($j=0;...;...)",
+#      because there exist perl versions that have problems with.
+#   2000/02/11 v1.12:
+#    * Option `clean' added.
+#    * The name of thumbnail data file: jobname.tnd,
+#      if thumbpdf is called: thumbpdf jobname[.pdf] [options]
+#   2000/02/22 v2.0:
+#    * pdfmark support for dvips/ps2pdf route added.
+#    * <jobname>.tpt replaces thumbdta.tex (for pdfTeX)
+#      <jobname>.tpm (for pdfmark)
+#      <jobname>.top replaces thumbopt.tex
+#    * Options `useps', `modes' added,
+#      `makedef' renamed to `makedata'.
+#   2000/02/28 v2.1:
+#    * Environment variable `THUMBPDF' supported.
+#   2000/03/07 v2.2:
+#    * Support for Distiller 3 and 4, the streams are uncompressed.
+#    * Call of gs is changed in order to show the currently processed
+#      page number of the pdf file.
+#    * Option --printgscmd creates the command line file `thumbpdf.gs'
+#      for the Ghostscript call.
+#   2000/03/22 v2.3:
+#    * Bug fix: --useps now works.
+#   2000/04/10 v2.4:
+#    * Fix for ActiveState Perl 5.6.0: uc line changed, fork removed.
+#      (Thanks to Andreas Buehmann <andreas.buehmann@gmx.de>.)
+#    * Version test for thumbpdf.tex added for users that
+#      mix versions, sigh.
+#   2000/07/29 v2.5:
+#    * `save' trick in call of ghostscript.
+#    * Undocumented option --gspages added.
+#   2000/09/27 v2.6
+#   2000/10/27 v2.7:
+#    * -dFIXEDMEDIA=0 added in gs call
+#   2001/01/12 v2.8:
+#    * Bug fix in dvips mode and active option `level2':
+#      pack parameter corrected for little-endian machines.
+#    * /Rotate in pdf pages:
+#      ghostscript versions around 6.01 have added a hack
+#      in /pdfshowpage_setpage, that ignores the /Rotate entry.
+#      A patch is added to disable the hack.
+#    * Ghostscript uses the MediaBox for calculating the
+#      page size. For version 6.50 a patch is added to use
+#      the /CropBox instead.
+#   2001/03/29 v2.9:
+#    * Option --password added.
+#   2001/04/02 v2.10
+#   2001/04/26 v2.11
+#    * Option --antialias added (suggestion of Juergen Bausa).
+#   2002/01/11 v3.0
+#    * Syntax of option --antialias changed (see readme.txt).
+#    * Support for VTeX's PS mode added.
+#    * Greek mode added (see readme.txt).
+#    * Signal handlers added for cleanup.
+#   2002/05/26 v3.1
+#    * SIG_HUP unkown in Windows.
+#    * Bug fix: The signal function for __DIE__ "cleanup" aborts
+#      before the error message of "die" is printed.
+#      Replaced by "clean" that does not contain "exit 1".
+#    * Small bug fix in mode detection and mode "vtex"
+#      removed from list. "vtexpdfmark" was detected,
+#      "vtex" did not work and perhaps it will be used
+#      later for VTeX in PDF mode.
+#   2002/05/26 v3.2
+#    * Fix: "MacOS/X: darwin" is now not interpreted as
+#      Windows.
+#   2003/03/19 v3.3
+#    * Fix for gs 8.00 in mode dvips:
+#      THB_DistillerPatch also applied to ghostscript >= 8.00.
+#   2003/06/06 v3.4
+#    * Bug fix, two forgotten "pop"s added for Distiller case.
+#   2004/10/24 v3.5
+#    * Revert Cygwin detection: is unix (request by Jan Nieuwenhuizen).
+#    * LPPL 1.3.
+#   2004/11/19 v3.6
+#    * Bug fix for dvips mode and gs < 8.00 (/stackunderflow in pop).
+#   2004/11/19 v3.7:
+#    * For easier debugging, the special thumbpdf objects of
+#      thumbpdf.pdf are now valid PDF objects (dictionaries).
+#    * Remove of extra '\n' before "endstream" that is added
+#      by pdfTeX 1.20a.
+#   2005/07/06 v3.8:
+#    * Fix because of pdfTeX 1.30.

+# NEWS:
+#   14 Jan. 2007 - make it executable shell script, calling awk
+#   16 Dec. 2004 - Replaced // {print} by {print} (some AWKs did choke)
+#   09 Apr. 2004 - Locale check: Decimal point in float numbers?
+#   30 Oct. 2003 - Replaced print statements by printf to avoid
+#   underflow numbers like 1e-14 in \pdfliterals. Remove trailing
+#   zeroes of floating point numbers.
+#   02 May  2003 - Lines starting with \ allow TeX insertions,
+#   e. g. of pdfTeX \pdfliteral{}
+#   29 Apr. 2003 - Changed for pic of groff 1.19
+#   16 Mar. 2003 - Bug corrected: Dashed lines shorter than minimum
+#   dash-pause length now drawn solid.
+#   11 Nov. 2002 - Spline drawing improved: First half of first and last
+#   half of last spline segments are drawn by straight lines.
+#   28 Nov. 2002 - Arc and circle drawing cleaned up. Full circle is now
+#   drawn by 4 Bezier curves, as is common use. Arcs split evenly into
+#   Bezier curves, to minimize max. error.
+#   02 Dec. 2002 - Experimental pic (groff > 1.18.1) with improved
+#   vertical picture positioning supported.
+#   04 Dec. 2002 - Experiment with modified pic (\vtop -> \vbox),
+#   Formula for Bezier constant c reduced.

+Depending on the name of the script `vpe' works in four modes:
+
+* [vpe] Syntax: vpe <pdf file>[.pdf]
+  The pdf file is scanned for actions created by VTeX,
+  that start an editor with the source file at the
+  specified line under Windows.
+  A symbol link is made from the source file name
+  extended by the extension `.vpe' to this script.
+  The line number is encoded in the path and the
+  action is changed to start this script.
+
+* [sty] Internal for vpe.sty:
+  Syntax: vpe --sty [--progname=...] <latex file> <vpe file>
+
+* [system] Internal for vpe.sty:
+  Syntax: vpe --system <vpe file>
+
+* [launch] Syntax: <source file name>.vpe
+  The script decodes the line number in the path of
+  the source file name and starts an editor with
+  this file at that line number.
+
+Options:
+  --help:     print usage.
+  --verbose:  print additional informations during running.
+  --force:    force symbol links
+  --delete:   delete symbol links
+  --sty:      internal for `vpe.sty' (get absolute file name and lines)
+  --system:   internal for `vpe.sty' (get system info linux or win)
+  --progname: latex, pdflatex, elatex, pdfelatex
