You are misreading the outer |: The extension is actually .al and
(AFAIK) files with this extension are generated by AutoSplit and
supposed to be used via AutoLoader (both are 'standard' Perl modules).

> is it necessary to include the “.pod”?

Actually, it seems to be wrong: The emacs version I'm using (22.2.1)
has a POD mode which does some 'fancy rendering' for .pod files (and
presumably, other stuff as well).
