Hmm... You're dead right , except for the location, which happens to be
{pnetlib_root}/runtime/System/IO/Directory.cs ... But I guess you knew
that already ..

An example is worth a hundred lines of explanation ... So since I'm
not inclined to type out hundred lines , I'm pushing this example
upto you ... Check out http://symonds.net/~gopalv82/code/Directory.tgz

It's an example of how I hack pnetlib without recompiling the whole of
pnetlib ... I pull all the "internal" dependencies into one dir and add
a String _(String) method for the error message I18n stuff to the class
and hopefully cscc *.cs works ... Else it's back to slumming it in the
compiler ..

And in your case it does , So best of luck with System.IO.Directory !
