*** The new variable rmail-file-coding-system specifies the code<BR>
conversion to use for RMAIL files.  The default value is nil.
<P>
When you read mail with Rmail, each message is decoded automatically
into Emacs' internal format.  This has nothing to do with
rmail-file-coding-system.  That variable controls reading and writing
Rmail files themselves.
