vsdump is an ALT Linux (www.altlinux.ru) project of VSD/VSS file format reverse engineering.
The project site is http://www.gnome.ru/fileformats/diagrams.html.

This project was started with Ian Redfern results (http://www.redferni.uklinux.net/visio/)
and was greatly improved by knowledges extracted from libgsf.
For discovered parts of format look into docs/vsdformat.txt.

Requirements:
libgsf (http://freshmeat.net/projects/libgsf).

Coding:
All good strings of code were stolen from Jody Goldberg and Morten Welinder works.
At the moment the code is considered to be a set of testing utilities
that support a process of format researching only.
By side effect it's also some kind of 'documentation' =)
