Pine is a user-agent for reading, sending, and managing
    electronic messages. It was originally developed at the
    University of Washington with novice users in mind, but can be
    tailored to accommodate the needs of more experienced users. The
    UNIX, DOS, and Windows versions are maintained by the Computing &
    Communications group at the University of Washington and can be
    obtained from ftp.cac.washington.edu via anonymous FTP. A mailing
    list for Pine is maintained as pine-info@cac.washington.edu;
    however, bugs found in the PMDF version of Pine should be
    reported to support@process.com.

    Pine has a full-screen interface which uses one-character
    mnemonic commands and control sequences for its command input.
    You do not have to hit the RETURN or ENTER key to finish a
    command. A command menu is always present at the bottom of the
    screen, and help is only one keystroke away. It is intended that
    Pine can be learned by exploration and the browsing of extensive,
    context-sensitive on-line help provided within Pine, but some
    basic concepts to get a new user started are discussed below.
