====== util.jid API ======
Prosody provides an API for manipulating JIDs in various ways.

===== Using =====
<code lua>
   local jid = require "util.jid";
</code>

===== Reference =====

==== jid.split(id) ====

Returns 3 strings, the node, host and resource. The node and/or resource may be nil (in the case of a bare or domain JID). The host will be nil only for invalid JIDs (in which case all returns will also be nil).

==== jid.prepped_split(id) ====

Same as jid.split(id), but runs stringprep over the JID before splitting.

==== jid.prep(id) ====

Returns the passed JID, after applying the stringprep rules.

==== jid.bare(id) ====

Returns the bare JID, that is the JID without any resource (if it had one).
