1.2 The Mail Room Class
*** To be updated for MOO 1.3 ***
This class provides the mail facility used within LambdaMOO. Some would say that to
provide an electronic mail facility within a game is slightly insane, but it is very useful for
passing around game related messages. Coupled with the use of a suitable client program,
for example the excellent mud.el with MOO Mail extensions, sending MOO mail can be
easy and efficient. It also allows players to separate their MOO based mail from other, more
important mail.
LambdaMOO does not yet provide any facility for reading input from a player. For
this reason, programs such as the mail room use a pseudo-room to catch player input.
For example, when you start to compose a mail message, you are transported to the mail
pseudo-room. Once there, anything you enter is trapped by various verbs in the room, and
stored in the message you are entering.
This method means that commands used in the mail composition environment are actually verbs on the mail pseudo-room.
Mail messages are actually stored on the player object, in a property list called messages.
Each message occupies one entry, called a mail record, in the following format:
{num, {date, from, to, subject, line1, ..., lineN } }
Apart from the num field, these are all strings. The num field stores the message number
for each message. When a new piece of mail arrives, it is allocated a message number 1
