Determine symlink name in required module

[vurt]

Hi,

I'm possibly not googling effectively, but I couldn't find an answer to
this.

Say I had a scriptanalogous something like:

require "/foo/bar/S01wibble.pm"

But the file is actually a symlink, ie:

/foo/bar/S01wibble.pm -> ../wibble.pm

How can I, in the required module, find the name of the symlink. I want to
be able to have behaviour analogous to rc scripts, and be able to have
different behaviour determined by the name I was called as. I hasten to
add I'm not actually trying to produce real rc scripts here...

Any tips would be welcome...

AFAIK the only thing you can do is grovel through values %INC looking
for a symlink to the right place. I suppose that if you remove or
replace it every time wibble.pm is loaded this would even be reliable.
