-# Reqirements: Perl5, Ghostscript
-# History:
-# 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.
