-remote command interpreter
+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 <TT>make_new_child</TT> 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,
