+This is a remote command interpreter on a TCP LON-CAPA network layer.
+It accepts and processes incoming requests from other LON-CAPA machines
+on the network. lond's functionality is self-contained in the sense
+that it does not reference (import, require, use) any other file
+described in this document. There are only 15 subroutines in this
+script, however the make_new_child subroutine is quite
+complex since it parses and responds about 29 different types of
+network requests (i.e. enc, ping, pong, ekey, load, auth, passwd,
+makeuser, home, update, unsub, sub, log, put, rolesput, get, eget,
+del, keys, dump, store, restore, querysend, queryreply, idput, idget,

+
+
+This module provides access to an educational resource construction area.
+This module is invoked by the URL-related pattern syntax
+LocationMatch "^/priv.*" or LocationMatch "^/\~.*".
+Authentication of user identity
+is coordinated through cookies. The abbreviation "cacc" corresponds
+to "construction-space access"). If the cookie handle is invalid, then
+this module returns a forbidden status and makes appropriate log entries.
+If the cookie handle is valid, status is determined to be okay (and,
+for the "priv"-type access, the resource is delivered by the
+lonconstruct module).

+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.
