[MacPerl] Perl script 4->5 checker

[Vicki Brown <vlb@cfcl.com>]

Does anyone know of / have access to a Perl script that will scan another
script (written for Perl 4) and report back on anything that could be a
problem with Perl 5.

(Yes, I know I can probably write one, but I'd rather leverage what someone
else has done; I'm being lazy).

Basically, it has to take note of things such as
   use of the single tick mark (now :: is preferred)
   use of dbmopen, dbmclose (no longer in vogue)
   use of keywords added in Perl 5 that weren't keywords before (e.g. my)

   what else?

We've got a few hundred scripts at work that were written with Perl 4 and
people are nervous about just running them under Perl 5.* without being
really _sure_ and no one has time to test each of these carefully. A sanity
checker would be useful.
