 AutoTeX is an automatic TeX processing system designed to
 process TeX/LaTeX/AMSTeX/etc source code of papers submitted
 to the (nee e-print archive. The
 portable part of this code has been extracted and is made
 available in the hope that it will be useful to other projects
 and that the input of others will benefit

 Code developed and contributed to by Tanmoy Bhattacharya, Rob
 Hartill, Mark Doyle, Thorsten Schwander, and Simeon Warner.
 Refactored to separate generic code from specific code
 by Stephen Marsh, Michael Fromerth, and Simeon Warner 2005/2006.

fix_ps_title($file, $title, $log)

Changes the %%Title line (the first occurrence) in the given PostScript file if found within the first 6 lines. $log is a TeX::AutoTeX::Log object to log errors.

stamp_postscript($file, $stampref, $log)

Adds a stamp to the PostScript file, and if $stampref specifies a link target as its second element, makes the stamp an active hyperlink.

Input parameters:

  file name relative to cwd
$stampref = [$stamp, $link]
 $stamp string to add
 $link URL to link stamp to (if set, otherwise no link)
 this is an _optional_ TeX::AutoTeX::Log object to log errors:
 $log set   => usual $log->verbose() and $log->error()
 $log undef => no logging, returns error code else 0 for OK


The placement of the stamp assumes US letter size paper (11.5in tall) and makes assumptions about the average character width at the given size. These are expedients that work well most of the time. Obviously these would need to be modified for say e-book reader formats.
