NAME
revertpdf.pl - Remove the last edits to a PDF document
SYNOPSIS
revertpdf.pl [options] infile.pdf [outfile.pdf]
Options:
-c --count just print the number of revisions and exits
-v --verbose print diagnostic messages
-h --help verbose help message
-V --version print CAM::PDF version
DESCRIPTION
PDF documents have the interesting feature that edits can be applied
just to the end of the file without altering the original content.
This makes it possible to recover previous versions of a document.
This is only possible if the editor writes out an 'unoptimized' version
of the PDF.
This program removes the last layer of edits from the PDF document. If
there is just one revision, we emit a message and abort.
The "--count" option just prints the number of generations the document
has endured and applies no changes.
