Tool for automated cleaning of ${prefix}/var/distfiles

> It might have the information available (I think we stored install-time Portfiles into the database) but I'm not sure if that's what we use when cleaning distfiles. A quick glance in your directory should confirm this, or a base dev looking into the source for it.

For example, I just updated boost to 1.54 and uninstalled 1.53, but I still find both files in the corresponding distfiles subdirectory:

Air > ll /opt/local/var/macports/distfiles/boost/
total 221960
-rw-r--r--  1 macports  admin  55765258 30 jui 16:18 boost_1_53_0.tar.bz2
-rw-r--r--  1 macports  admin  57873778 22 jul 20:21 boost_1_54_0.tar.bz2
