grepmail version 3.6

Grepmail searches a normal or gzip'ed mailbox for a given regular expression,
and returns those emails that match it. Piped input is allowed, and date
restrictions are supported.

New in version 3.7:
- Added -D for debugging output
- Now ignores ASCII files that don't look like mailboxes
- Uses Date::Parse instead of Date::Manip, which results in faster execution
  time at the expense of less flexibility. (e.g. You can't do "12pm January 5
  1997" any more)

New in version 3.6:
- No more temporary files! This addresses the security issues that a few
  people have sent me email about. The new version uses a bit more memory,
  depending on the size of the largest email in your mailbox. It's quite a bit
  faster for piped input, though. Many thanks go to Joey Hess who supplied
  insights and contributions toward making this release happen, especially the
  buffering code.

Send me email if you would like to be notified of updates.

Please send me any modifications you make. (for the better, that is. :) I have
a suite of tests that I can give you if you ask. Keep in mind that I'm likely
to turn down obscure features to avoid including everything but the kitchen
sink.
