DO NOT USE THIS PLUGIN. YOU DO NOT NEED IT. GO HERE INSTEAD...
The Eclipse Team Provider for git repositories, EGit, requires Eclipse 3.5 or greater. To accommodate DDE users, I have taken the source code and removed all references to 3.5 requirements. The vast majority of these were for debug tracing anyway, and were therefore only useful to the core developers.
A few other small changes were made for resolving constants only defined in 3.5 or working around methods with argument signatures that only exist in 3.5.
This plugin won't be very useful if you don't also have http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=Source%20Control%20Enablement%20for%20Designer
If you're wondering why you should work with git repositories, rather than CVS or SVN or Hg, watch this: http://www.youtube.com/watch?v=4XpnKHJAok8 Or just try it out and actually make local branches of your NSF and merge them. It is unbelievably cool.
