Where to get it.
The TrackChanges GUI is currently beta software. Beware, bugs may lie in wait.
I have not yet made any binary packages for the GUI. Until I do, an installation of Python and PyQt are necessary. Instructions can be found in the README file.
The LaTeX style file can be used without the GUI in any case.
To download the latest version of the TrackChanges package go the SourceForge project
