As noted here I am working on a conversion of a ClearCase repository to Subversion. Since there appear to be no resources for this available I wrote a simple perl script that handles the conversion in a relatively simplistic manner. In short, it checks out each version of a ClearCase file and checks it into Subversion, therefore creating the history. It's simple but effective and it worked quite well to convert our entire repository (some 30+ hours for the whole thing..).

Anyone who wants it, it's here, but please make sure to read the documentation, particularly the limitations before you attempt to use this thing.. and by all that is holy, run a test run and backup!
