/**
* - PSYC defines standard variables, methods, etc. This
* library deliberately abstracts over all of these; a
* higher-level API should combine the naming system (GNS)
- * and standard methods (message, join, part, warn,
- * fail, error) and variables (action, color, time,
- * tag, etc.). However, this API does take over the
- * routing variables, specifically 'context' (channel),
- * and 'source'. We only kind-of support 'target', as
+ * and standard methods (_converse, _notice, _request,
+ * _warning, _error etc) and variables (_action, _color,
+ * _time, etc). However, this API does take over the
+ * routing variables, specifically '_context' (channel),
+ * and '_source'. We only kind-of support '_target', as
* the target is either everyone in the group or the
* origin, and never just a single member of the group;
* for such individual messages, an application needs to
* implementing defaults for standard methods and
* variables might be called 'PSYC-std' or 'PSYC-high'.
*
+ * In PSYC terminology this is simply called the "PSYC
+ * routing layer" and the abstractions, for instance in
+ * psyced, are quite similar. The higher one is called
+ * "PSYC entity layer." In the text rendering of the
+ * protocol the two are separated by an empty line. See
+ * http://about.psyc.eu/Spec:Packet and related. --lynX
