b2m - convert old Emacs Rmail Babyl format to mbox format
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 standard output. Babyl was the storage format used by Rmail prior to Emacs 23.1. Since then, it uses standard mbox format. This program is distributed with GNU Emacs.
The program accepts unambiguous abbreviations for long option names. -V, --version Display version information. -h, --help Display basic usage information.
The Babyl format is described in the file etc/BABYL in the Emacs distribution. 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.
