+The test-binhdr* files were supplied by Martin von Gagern, constructed
+as follows.  They contain binary junk before the EPS starts.  We also
+use these to test different line endings.  These files are public domain.

+.TH EPSTOPDF 1 "30 November 2009"
+.\" $Id: epstopdf.1 16245 2009-11-30 01:37:26Z karl $
+.\" man page originally by Jim Van Zandt
+.SH NAME
+epstopdf, repstopdf \- convert an EPS file to PDF
+.SH SYNOPSIS
+\fBepstopdf\fP [\fIoptions\fP] [\fIepsfile\fP]
+.SH DESCRIPTION
+\fBepstopdf\fP transforms the Encapsulated PostScript file \fIepsfile\fP
+(or standard input) so that it is guaranteed to start at the 0,0
+coordinate, and 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.  By default, the
+result is piped to Ghostscript and a PDF version written.
+.P
+If the bounding box is not right, of course, there are problems.
+.SH OPTIONS
+.IP "\fB--outfile\fP=\fIfile\fP"
+write result to \fIfile\fP; the default is to construct the output file
+name by replacing any extension in the input file with \fI.pdf\fP.  If
+\fB--nogs\fP or \fB--filter\fP is specified, write to standard output.
+.IP "\fB--\fP[\fBno\fP]\fBcompress\fP"
+use compression (default: on).
+.IP "\fB--\fP[\fBno\fP]\fBdebug\fP"
+write debugging info (default: off).
+.IP "\fB--\fP[\fBno\fP]\fBembed\fP"
+embed fonts (default: on).
+.IP "\fB--\fP[\fBno\fP]\fBexact\fP"
+scan ExactBoundingBox (default: off).
+.IP "\fB--\fP[\fBno\fP]\fBfilter\fP"
+read standard input (default: off).
+.IP "\fB--\fP[\fBno\fP]\fBgs\fP"
+run ghostscript (default: on).
+.IP "\fB--\fP[\fBno\fP]\fBhires\fP"
+scan HiresBoundingBox (default: off).
+.IP "\fB--gscmd\fP=\fIval\fP"
+pipe output to \fIval\fP (default: [\fBgswin32c\fP on Windows, else \fBgs\fP])
+.IP "\fB--res\fP=\fIdpi\fP"
+set image resolution (default: [use gs default])
+.IP "\fB--autorotate\fP=\fIval\fP"
+set AutoRotatePages (default: None); recognized \fIval\fP choices:
+None, All, PageByPage.  For EPS files, PageByPage is equivalent to All.
+.IP "\fB--restricted\fP=\fIval\fP"
+turn on restricted mode (default: [on for resptopdf, else off]);
+this restricts the values accepted by \fB--gscmd\fP and impose restrictions
+on the output file name similar to web2c's openout_any=p.
+.IP "\fB--help\fP
+display help message and exit
+.IP "\fB--version\fP
+display version information and exit
+.SH EXAMPLES
+Examples for producing "test.pdf":
+.nf
+epstopdf test.eps
+produce postscript | epstopdf --filter >test.pdf
+produce postscript | epstopdf -f -d -o=test.pdf
+
+.fi
+Example: look for HiresBoundingBox and produce corrected PostScript:
+.nf
+epstopdf -d --nogs --hires test.ps >testcorr.ps 
+.fi
+.SH BUGS
+The case of "%%BoundingBox: (atend)"
+when input is not seekable (e.g., from a pipe) is not supported.
+.PP
+When reporting bugs, please include an input file and command line
+options so the problem can be reproduced.  Report bugs in
+the program or this man page to tex-k@tug.org.

+# This is a script to transform an EPS file such that:
+#   a) it is guaranteed 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, there will be problems.
+#
+# One thing not allowed for is the case of
+# "%%BoundingBox: (atend)" when input is not seekable (e.g., from a pipe),
+# which is more complicated.

+# emacs-page
+# History
+#  2009/11/27 v2.12 (Karl Berry)
+#    * Make --filter work again
+#  2009/11/25       (Manuel P\'egouri\'e-Gonnard)
+#    * Better extension detection, suggested by A. Cherepanov.
+#  2009/10/18       (Manuel P\'egouri\'e-Gonnard)
+#    * Better argument validation (Alexander Cherepanov).
+#    * Use list form of pipe open() (resp. system()) to prevent injection.
+#    Since Perl's fork() emulation doesn't work on Windows with Perl 5.8.8 from
+#    TeX Live 2009, use a temporary file instead of a pipe on Windows.
+#  2009/10/14       (Manuel P\'egouri\'e-Gonnard)
+#    * Added restricted mode.
+#  2009/09/27 v2.11 (Karl Berry)
+#    * Fixed two bugs in the (atend) handling code (Martin von Gagern)
+#    * Improved handling of CR line ending (Martin von Gagern)
+#    * More error checking
+#    * --version option
+#    * Create source repository in TeX Live
+#  2009/07/17 v2.9.11gw
+#    * Added -dSAFER to default gs options
+#	TL2009 wants to use a restricted variant of -shell-escape,
+#	allowing epstopdf to run. However without -dSAFER Ghostscript
+#	allows writing to files (other than given in -sOutputFile)
+#	and running commands (through Ghostscript pipe's language feature).
+#  2009/05/09 v2.9.10gw
+#    * Changed cygwin name for ghostscript to gs
+#  2008/08/26 v2.9.9gw
+#    * Switch to embed fonts (default=yes) (J.P. Chretien)
+#    * turned no AutoRotatePages into an option (D. Kreil) (default = None)
+#    * Added resolution switch (D. Kreil)
+#    * Added BSD-style license
+#  2007/07/18 v2.9.8gw
+#  2007/05/18 v.2.9.7gw (Gerben Wierda)
+#    * Merged both supplied 2.9.6 versions
+#  2007/05/15 v2.9.6tp (Theo Papadopoulo)
+#    * Simplified the (atend) support
+#  2007/01/24 v2.9.6sw (Staszek Wawrykiewicz)
+#    * patched to work also on Windows
+#  2005/10/06 v2.9.5gw (Gerben Wierda)
+#    * Fixed a horrendous bug in the (atend) handling code
+#  2005/10/06 v2.9.4gw (Gerben Wierda)
+#    * This has become the official version for now
+#  2005/10/01 v2.9.3draft (Gerben Wierda)
+#    * Quote OutFilename
+#  2005/09/29 v2.9.2draft (Gerben Wierda)
+#    * Quote OutFilename
+#  2004/03/17 v2.9.1draft (Gerben Wierda)
+#    * No autorotate page
+#  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!)
+#  2002/02/21 v2.8draft (Gerben Wierda)
+#    * Fixed bug where last line of buffer was not copied out (ugh!)
+#  2002/02/18 v2.8draft (Gerben Wierda)
+#    * Handle different eol styles transparantly
+#    * Applied fix from Peder Axensten for Freehand bug
+#  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.
+#  2000/11/05 v2.6 (Heiko Oberdiek)
+#    * %%HiresBoundingBox corrected to %%HiResBoundingBox
+#  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;';
+#
+# Thomas Esser, Sept. 1998: change initial lines to find
+# perl along $PATH rather than guessing a fixed location. The above
+# construction should work with most shells.

+# Originally by Sebastian Rahtz, for Elsevier Science
