.TH MU-SERVER 1 "December 2011" "User Manuals" .SH NAME mu server \- the mu backend for the mm e-mail cleint .SH DESCRIPTION \fBmu server\fR starts a simple shell in which can manipulate the mu database. The output of the commands is terms of symbolic expressions (s-exps). \fBmu server\fR is not meant for use by humans; instead, it is designed specifically for the \fBmm\fR e-mail client. .SH OUTPUT FORMAT \fBmu server\fR accepts a number of commands, and delivers its results in the form: \\376\\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 .SH AUTHOR Dirk-Jan C.
