Automatically parsing MIME files in rmail

[Craig Smilovitz <craig@theworld.com>]

I use emacs rmail for mail reading.  I seem to remember that in a 
previous emacs I used (on a different machine) there was a function that 
would automatically parse a MIME message and deposit its components in 
separate files in a subdirectory.  I executed this function manually 
from the RMAIL buffer using M-x <function name>.

I don't remember what the function was called.  Does anyone know what it 
was and extra credit if you can tell me where I can get an 
implementation of this function.  As far as I can determine, it doesn't 
appear to be a function in my current installation.

When I look at the emacs documentation, it describes a lot of functions 
mm-* that do low-level mime parsing operations.  My assumption is that 
these are the guts that are called by the lisp macro that I want.  But 
the distance from the mm-* functions to what I want seems too great to 
try and write the top level function myself.

Thanks a lot.
