Description:

[.KILLER]
	Idle Job Killer. You've seen 'em before, you'll see 'em again.
	This one incorporates the "BREAK BUSTER" program from the
	previous tape; it can be extracted with little or no pain.
	THIS WORKS UNDER V4.x AND NOT UNDER V3.x !!!

[.CROSS_MAIL]
	Have a network? Have people not really knowing what node people
	are on, yet knowing their username?  Use CROSS_MAIL nightly
	for relief of pains associated with this.  Essentially, what
	this program does is take everyone on THIS node (ie, the node
	that the program is run on) and put an entry in VMSMAIL.DAT
	on THAT node (CROSS_MAIL.COM asks for a name for THAT node; you'll
	need to give access control if appropriate) which forwards all
	mail sent on THAT node to people on THIS node to THIS node.  

	So, assuming that all people have ONE username, and that you
	have a small network, no one has to know what node people
	get their mail on; VMSMAIL knows automagically. 

	Make sense?  If you don't get it, you probably haven't recognized
	the problem yet.

	PLEASE, PLEASE, PLEASE, READ THE .COM FILE BEFORE RUNNING THIS
	PROGRAM.

[.PURGE_MAIL]
	Deleted a user lately? Wonder what happens to their entry in
	VMSMAIL.DAT when you do so?  I'll tell you -- it sticks around.
	Forever. And ever. And ever.

	So, run PURGE_MAIL once a month, and it cleans out any entries
	in VMSMAIL that don't have usernames in SYSUAF.  "But, like, 
	I have special pointers in VMSMAIL."  Well, so do we, so a
	file called XCEPTS (usually in SYS$LIBRARY, but this is driven
	by a .COM file, so don't worry, you non-hackers you) lists
	names that SHOULDN'T be deleted.  For example, we direct mail
	sent to SYSTEM to someplace else; there's a corresponding entry
	in XCEPTS which simply says "SYSTEM," and instructs PURGE_MAIL
	to leave that one alone.

	NOTE: Xcepts is an indexed file, and the .COM file which runs
	MAIL_PURGE tries to deal with that.  Thus, if you went and edited
	the file (which is certainly a legitemite thing to do), the
	.COM file will try to $ CONVERT the file back.  For this reason,
	there's an FDL file which has to go along with the program.

	PLEASE, PLEASE, PLEASE, READ THE .COM FILE BEFORE RUNNING THIS
	PROGRAM.
