74 * use this to sync chats in buddy list on multiple clients?
75 *
76 * - cmd:bccontext
77 * send after cmd:join to trigger rpl:bccontext
78 *
79 * - rpl:bccontext
80 * according to available documentation delivers channel history, etc.
81 * [no log file examples]
82 * can we add the history to the window when we open the window, or would
83 * that confuse users that use history based on client log?
84 *
85 * - cmd:getinv
86 * <inv inviteId="1" domain="<DOMAIN>" />
87 * rpl:getinv
88 * ???
89 *
90 * according to documentation should provide list of outstanding invites.
91 * [no log file examples]
92 * should we automatically join those channels or ask user to join/add?
93 *
94 * - chatserver_command_message()
95 * needs to support multiple <chatgrp> nodes?
96 * [no log file examples]
97 *
