+Mutt
+----
+
+If you use the [[Mutt]] email client (or just want a simple way to
+query email addresses from the command line) there are a [number of
+scripts][mutts] available.  Pick whichever sounds most appealing to
+you.  I wrote up [[mutt-ldap.py]], which lets you configuration the
+connection details via a config file (`~/.mutt-ldap.rc`) rather than
+editing the script itself.  Usage details are available in the
+docstring.
