Err... It would be nice if prcs2svn did clean its temp files.
By the way, I would suggest a complete change of temp dir scheme.
Instead of putting everybody directly in /tmp, I would create
/tmp/prcs2svn-PROJECT-XXXXX
and inside I would create
prcs/
migrate/
svn/
etc.
That would avoid the clutter, and would make cleaning easier (both
automatically, and by hand).
