+# Change by Thomas Esser, Sept. 1998: The above lines allows us to find
+# perl along $PATH rather than guessing a fixed location. The above
+# construction should work with most shells.
+
+# A script to transform an EPS file so 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, 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
+# 2007/01/24 v2.9.6sw (Staszek Wawrykiewicz)
+# * patched to work also on Windows
+# 2007/05/15 v2.9.6tp (Theo Papadopoulo)
+# * Simplified the (atend) support
+# 2007/05/18 v.2.9.7gw (Gerben Wierda)
+# * Merged both supplied 2.9.6 versions
+# 2007/07/18 v.2.9.8gw
+# 2008/08/26 v.2.9.9gw
+# * 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
