pdfresurrect - 0.15-2 main

PDFResurrect is a tool for analyzing and manipulating revisions to
PDF documents (sometimes known as Adobe Acrobat files). The PDF format
allows for previous changes to be retained in a revised version of the
document, thereby keeping a running history of revisions to the document.
.
This tool extracts all previous revisions while also producing a summary
of changes between revisions. It can also "scrub" or write data over the
original instances of PDF objects that have been modified or deleted, in
an effort to disguise information from previous versions that might not
be intended for anyone else to read.
