The package I use to do the mirroring is actually called "mirror" and is a set of PERL scripts...

That's what gets me - 0.01 is provided in gz and bz2 format, as is 0.12, but the rest of the 0.xx series are mainly only provided in .Z format...

Perhaps they should be added - after all, gunzip handles .Z as well as .gz archives...
Best wishes from Riley.
