I was used to cvs-purge from cvstools, so the extension was called purge.

Recently I noticed that other SCM have the same functionality under the 
'clean' name, like git-clean, svn-clean (from the subversion-tools 
package), and bzr clean-tree (from bzrtools), so I thought that some new 
user could find the alias useful, given that the change is minimal.
