+=head1 NAME
+
+Apache::lonnet.pm
+
+=head1 SYNOPSIS
+
+This file is an interface to the lonc processes of
+the LON-CAPA network as well as set of elaborated functions for handling information
+necessary for navigating through a given cluster of LON-CAPA machines within a
+domain. There are over 40 specialized functions in this module which handle the
+reading and transmission of metadata, user information (ids, names, environments, roles,
+logs), file information (storage, reading, directories, extensions, replication, embedded
+styles and descriptors), educational resources (course descriptions, section names and
+numbers), url hashing (to assign roles on a url basis), and translating abbreviated symbols to
+and from more descriptive phrases or explanations.
+
+This is part of the LearningOnline Network with CAPA project
+described at http://www.lon-capa.org.
