MBU, UTILITIES, A Utility for VMS Mailboxes
  MBU is a utility for VMS mailboxes. MBU can create mailboxes,
  delete mailboxes, read and write mailbox messages, and display and 
  change the characteristics of mailboxes. It can also view messages in a 
  mailbox without reading them.

  There is support for command files and scripts of mailbox messages to be
  repeated.

  This program was written by Ian Miller.

  WARNING

  The SET, SHOW and VIEW commands execute some kernel mode code to access
  system data structures. This requires CMKRNL privilege. This code appears
  to work on my system (AlphaVMS V7.3-2) but I can't say if it will work on 
  yours. It may crash your system. If you run without CMKRNL privilege then
  MBU will work except for VIEW and SET MAILBOX commands. (SHOW MAILBOX works
  but displays less information).
    
  MBU has been built on the following versions of AlphaVMS and appears to work
  V6.2, V7.1, V7.2-1, V7.3-1, V7.3-2.

  MBU does not build or work on VAX/VMS. I hope to fix this one day - any help
  appriciated.

  CHANGES
  V1.3 	Port to Alpha, display extra information 
  V1.4 	Show if mailbox is permanent or temporary. 
 	Display mailboxes matching specified criteria e.g. not empty.
	Display I/O queues for mailbox.
	Implement SET VERIFY, SHOW VERSION commands.

  TO BUILD MBU

  Either use MMK/MMS and MBU.MMS 

	MMK/DESCRIP=MBU.MMS
  
  (add /MACRO=DEBUG=1 to build a debug version)

  or use the DCL procedure B_MBU.COM

  	@B_MBU.COM

  (add a parameter of DEBUG to build a debug version)

  There is a MBU.HLP for insertion into SYS$LIBRARY:HELPLIB.HLB
