Munge-o-Matic is a project I've been working on for some time now - although this is the first official release it's actually the 3rd re-write of the code.
The thought behind the project was to have one small tool that could extract and rebuild a variety of the more common 'munge files'.
This first release version has 'plugin technology' so it's easy to keep the tool up-to-date with new code for different munge files in the form of plugin dll files.
Currently it has 3 plugin files with initial release but I will be adding more over the next few days.
