+=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 Szabó Péter <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.
