+What is python-ldap?
+--------------------
+
+* python-ldap provides an object-oriented API to access LDAP
+  directory servers from `Python`_ programs.
+* For LDAP operations the module wraps `OpenLDAP`_'s
+  client library *libldap* for that purpose.
+* Additionally the package contains modules for other LDAP-related stuff:
+
+  * LDIF
+  * LDAP URLs
+  * LDAPv3 subschema
