DeveloperGuide

setting up developer SVN access: https://gna.org/svn/?group=wesnoth
Keep the commit easy to revert if need be
no huge commit (hard to review), so when possible maybe split it in working part with info about where you are going
be on #wesnoth-dev IRC channel and coordinate with other developers
code should compile and work after commit
Don't mess with the art or music without approval from one of the art and music people.
clear commit message (can be several lines)
mention "bug #1234" in the commit message for automatic cc to that gna bug number
don't forget changelog
change status of fixed bugs to "Fixed" when committed
change status of fixed bugs to "Closed" when released, see ReportingBugs#Bug_protocol for details
register to commit mailing list: https://mail.gna.org/listinfo/wesnoth-commits
- or get the list moderator to approve commit messages from you otherwise
don't forget http://www.wesnoth.org/wiki/EasyCoding if you're ever out of ideas :)
