+Apache::lonnet - Subroutines to ask questions about things in the network.
+

+
+Invoked by other LON-CAPA modules, when they need to talk to or about objects in the network.
+
+ &Apache::lonnet::SUBROUTINENAME(ARGUMENTS);
+
+Common parameters:

+=over 4
+
+=item *
+
+$uname : an internal username (if $cname expecting a course Id specifically)
+
+=item *
+
+$udom : a domain (if $cdom expecting a course's domain specifically)

+
+=head1 OVERVIEW
+
+lonnet provides subroutines which interact with the
+lonc/lond (TCP) network layer of LON-CAPA. They can be used to ask
+about classes, users, and resources.
+
+For many of these objects you can also use this to store data about
+them or modify them in various ways.
+
+=head2 Symbs
+
+To identify a specific instance of a resource, LON-CAPA uses symbols
+or "symbs"X
