b2m < babyl-file > mbox-file
b2m accepts Babyl format mail (as used by older versions of Rmail in
GNU Emacs) on standard input, and converts it to mbox format on stan-
dard output. Babyl was the storage format used by Rmail prior to Emacs
23.1. Since then, it uses standard mbox format. This program is dis-
tributed with GNU Emacs.
The program accepts unambiguous abbreviations for long option names.

The Babyl format is described in the file etc/BABYL in the Emacs dis-
tribution. Rmail is documented in the GNU Emacs manual, which you
can read using Info, either from Emacs or as a standalone program.
b2m was originally written by Ed Wilkinson. Francesco Potorti updated
it according to the GNU coding standards.
