  10 PURPOSE: To describe an electronic message handling system.  The report
  11 outlines the implementation and provides complete user level documentation
  12 for efficient utilization of a new computer utility.

  17 DISCUSSION:  The MH message handling system was designed and implemented
  18 to  provide  comprehensive electronic message facilities.  It implements
  19 no new facilities which are not available in other message systems,  but
  20 its  close  integration  with  the system's command interpreter lends it
  21 more power and flexibility than is otherwise available.  Rather  than  a
  22 standard  implementation  in  which  all  of  the  functions  of message
  23 handling are implemented in one monolithic program, MH is  a  collection
  24 of  loosly  coupled  programs,  each  of  which implement one particular
  25 aspect of message handling.
  26      This implementation strategy has been found to be very flexible and
  27 easy  to  use.  Rather  than  having  to learn a new set of commands and
  28 conventions for interacting with  the  message  system,  users  use  the
  29 standard  system  command facility which they are already familiar with.
  30 Also, each module is relatively small, easy to debug and modify, and new
  31 modules  are  easy  to  add in a completely transparent manner.  Another
  32 important design feature of MH is its use of the operating  system  file
  33 facilities  directly.  That  is,  there  are  no monolithic message data
  34 bases,  rather  messages  are  stored   as   individual   files   within
  35 directories, which act as message folders.  Thus, all standard utilities
  36 are available on the messages without  having  to  code  them  into  the
  37 message system itself.
  38      Finally, each user of MH has a personal profile which allows for
  39 tailoring of each command.  With these facilities, users are able to
  40 start using the package immediately, and to enhance their interface as
  41 they gain knowledge of their own usage patterns.
