0.04 One-line change to modversion so it doesn't barf if the
module isn't installed
0.03 Now uses File::Spec for platform independence
(patch provided by Ville Skyttä <ville.skytta@iki.fi>)
Included a script, "modversion", to easily find a module's
version.
Now sets $m->{dir} even if it can't find a version.
0.02 Removed an unnecessary debugging "print"
0.01 Original version
