[Alpine-info] Examining contents of alpine's passfile?

The passfile is obfuscated (a throw-back to the days before strong crypto 
was available), and there is no standalone utility to de-obfuscate it.

The source is in alpine/imap.c, in xlate_in() and xlate_out().

Once, when I had a similar need, I took those routines and dropped them 
more-or-less verbatim into perl, and it worked as expected.  YMMV...
