Attached perl scripts:

uncheckout_post.tgr
Removes /0 branch at uncheckout time. This only works if the version is the last version on the branch and unlabelled.
mkelem_pre.tgr
Prevents so-called "evil twins", two different elements by the same name occupying different versions of the same director, also preventing mkelem when the files differ only in case.
