mthread — arrange messages into discussions

       Leah Neukirchen <leah@vuxu.org>

mthread  groups  messages  together in parent/child relationships, based on which messages are replies to
       which others.  (See mmsg(7) for the message argument syntax.)

       If no messages are specified, mthread will read filenames from the standard input,  or  use  the  default
       sequence if used interactively.

       mthread  prints  the threaded messages separated by newlines and indented according to their depth in the
       message tree.  Unresolved Message-IDs are printed as-is.

       The options are as follows:

       -v      Do not prune unresolved Message-IDs at the top-level.

       -p      With -S, only add parents, not unrelated subthreads.

       -r      Sort the top-level threads in reverse order (newest threads first).

       -Smsg  Treat msg as optional message(s) that will be added to  threads  only  if  they  are  referenced.
               Threads  where all messages are optional are suppressed.  You can use -S to add an outbox folder,
               for example, completing threads where your replies were missing.

       The mthread utility exits 0 on success, and >0 if an error occurs.
