 .SH NAME
 
-mu server\-  start a mu process which accepts commands
+mu server \- the mu backend for the mm e-mail cleint

-.SH SYNOPSIS

-.B mu server
 
 .SH DESCRIPTION
 
-\fBmu server\fR is the \fBmu\fR sub-command for starting a mu server process
+\fBmu server\fR starts a simple shell in which can manipulate the mu
-which accepts various commands (see below).  \fBmu server\fR is specifically
+database. The output of the commands is terms of symbolic expressions
-designed for communication with the emacs-text editor, and as such, the output
+(s-exps). \fBmu server\fR is not meant for use by humans; instead, it is
-is in the form of s-expressions.
+designed specifically for the \fBmm\fR e-mail client.
 
-\fBmu server\fR could be use as a very rudimentary interactive shell, but we
+.SH OUTPUT FORMAT
-would recommend the `muile' instead, which is much more powerful and suitable
-for humans.
 
-.SH OPTIONS
+\fBmu server\fR accepts a number of commands, and delivers its results in
+the form:
 
-.SH RETURN VALUE
+ \\376<length>\\376s-expr
+
+\\367 (that is, the character with ascii value 254, \\376 in octac notation),
+followed by the length of the s-expression, followed by another \\376,
+followed by the actual s-expression.
+
+By prefixing the expression with length, it can be processed more
+efficiently. The \\376 (254) was choses since it is a value that will never
+occur in valid UTF-8 (in which the s-expressions are encoded).
+
+.SH COMMAND AND RESPONSE
 
-\fBmu server\fR returns 0 upon success, and some other value when an error
-occurs. See \fBmu(1)\fR for a list.
