i assume in svn you create a tag by copying the tree, but then the cvs2svn importscript seems to create another commit on top of that, making the tag effectively a branch.
Can you give me an example of two such commits (by revision number or otherwise)? As far as I have seen, the tag is always created with a single commit. For example, the tag 'Release-0-2-internal' is created in revision 238, and there are no other checkins which touch the path tags/Release-0-2-internal.
