You'll need to have a set of rules for how each package puts its version
number in the filename. Generally this is of the form
"package-x.y.z.tar.gz", but you'll have to deal with issues like
"package2-x.y.z.tar.gz" and "pack-age-x.y.z.tar.gz" and
"package-beta.n-x.y.z.tar.gz", etc. -- there's no standard way of doing
this.

Then, use one of the many available text parsers (given the complication,
this is probably a job for perl) to extract the number you want.
