palm sync option #83768

Ok, I didn't want to go messing around with some of the other large
packages so I thought I would quickly write a perl script to do
various merging of data and write it back to the palm and back to
bbdb.  The result: a lot more wasted time than I was originally
planning on.  However, it does actually work.  It's only requirement
is to have a recent pilot-link installed...

Fundamentally it does this:

  0) saves N backup copies of previous files and the .bbdb file just
     in case.
  1) calls gnudoit to call bbdb-to-pilot-file to save a CSV from the
     jwz code.
  2) calls pilot-addresses to save a CSV from the pilot
  3) compares both of the above plus an archive from last run looking
     for matches and doing appropriate things when possible.  It
     doesn't currently handle modifications to a record on both sides
     though.  I am, however, planning on handling that in the future.
  4) writes out a CSV file for the pilot and the new "archive" for
     comparing against next time.
  5) calls pilot-addresses to delete the old BBDB category. (*)
  6) calls pilot-addresses to load the new merged archive into the
     BBDB category.
  7) calls gnudoit to load a bunch of elisp that was written by the
     sync program to modify bbdb-records.

Overall, I think this is working fine.  I haven't done a huge amount
of playing with it yet, but I just ran it successfully today to get it
to merge things together after BBDB had changed quite a bit.  Large
changes to the pilot records aren't well supported yet (new contacts
don't get auto-turned into elisp code yet, for example) but simple
ones are (phone number changes, etc).

Anyone interested?  Anyone think I'm doing something horribly wrong in
the above algorithm?
