+#   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.
