To create a patch, run svn diff [your_modified_files_here] > your_patch and then email the newly created "your_patch" file to
the developers' mailing list.
Keep your patches simple. If you changed lots of stuff, split it up
into smaller patches to make it easier for us to review. There's an
excellent
justification for
this over on the Bugzilla
site.
Send them to our developer's mailing list
(mixxx-devel).
Patches get reviewed quicker when there's more people looking at
them. This also gives us a means of discussing patches.
