NAME

     mthread — arrange messages into discussions

SYNOPSIS

     mthread [-v] [-S msg] [msgs ...]

DESCRIPTION

     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.

     -S msg  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.

EXIT STATUS

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