Remove the port for Pine, and the slave port for Pico. UW has discontinued
development on the Pine branch, and is instead focusing its efforts on the
successor, Alpine. http://www.washington.edu/alpine/
Alpine has more features, much better localization, better organized
(and largely rewritten) code, is BSD licensed, and should be a drop-in
replacement in terms of configuration files.
Alpine version 1.00 was released on March 17, 2008 after over a year of
development and community testing, and has since had 2 releases for
bugfixes and new features, so it's safe to say that this is a mature
replacement.
