XP Symlinks Confuse Subversion No End
Word to the wise: do not combine Windows symlinks with Subversion; it cannot handle them:
G:\svn\websites>svn add foo
G:\svn\websites>svn commit -m "message"
svn: Commit failed (details follow):
svn: File not found: transaction '39-1', path '/websites/foo'
This seems to hold true no matter which side of the symlink on which you work.
That's a bummer.
