Finding a CVS Commit and Turning It into a Patch
Pretty cool functionality in the NetBeans 5.0 CVS support I ran into the other day. Let's say you committed a fix to a branch and you need to create a patch of the fix, probably to post to a bug report and have it evaluated before you merge it back to the trunk or a bugfix branch. But the fix was over like a thousand files and you can't remember all of them.
Easy. First make sure that all the projects you committed on are open in the Projects window. Right-click any of the files you know was committed in the fix and choose CVS | Search History. You'll get the full history, with a little link for each that says Find Commit in - Open Projects.

Just click that link and you'll automatically get the list of all the files that were committed in with the Commit. You can check out diffs by clicking the Diff tab.
Now saving as a patch - with the Search History tab selected in the Source Editor, choose CVS | Export "blah-blah-blah [Search History] Diff as Patch.
And Bob's your uncle.
