NAME

revertpdf - Remove the last edits to a PDF document

SYNOPSIS

 revertpdf [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.
