No I haven't searched the monastery explicitly, normally google is pretty good in digging them out. (probably I was only relying on DDG, though.)

This post looks interesting but as far as I was able to decipher between all the HTML errors, it's mainly describing the API of Alien::SVN and not how to enforce a commit.

Anyway I had an interesting chat with TomFahle on our local PerlMongers meeting and he had once a similar project. In his opinion Tortoise SVN is pretty messed up and my only chance be

• identify all conflicting files with svn cleanup
• moving the conflicts safely away
• running svn up to get the old (conflict free) versions reestablished
• moving the files back overwriting the old versions again while losing the conflict
• now commiting

Haven't tested this approach yet, but it sounds promising. :)
