* b2m - a filter for Babyl -> Unix mail files
|
|
*
|
|
* usage: b2m < babyl > mailbox
|
|
*
|
|
* I find this useful whenever I have to use a
|
|
* system which - shock horror! - doesn't run
|
|
* Gnu emacs. At least now I can read all my
|
|
* Gnumacs Babyl format mail files!
|
|
*
|
|
* it's not much but it's free!
