I've played a bit with git-fast-import, but I sort of failed to get something working for PVCS export (see other thread).

The import-tars.perl script, however, was a very good idea. The simplest solutions for the multiple-directories source I had was just to tar it up and feed through import-tars.perl. After importing it into Git and repacking it with a suitably large --window argument, I had a Git repository of 64 megabytes, down from the four or so gigabytes of uncompressed directories. That did include removing some object files, though (but keeping some .exe's).
