Last change on this file since f959495 was 75a4b85, checked in by Wilmer van der Gaast <wilmer@…>, at 2006-07-14T09:25:48Z
Fixed a memory leak, added a check for valid Jabber handles, and updated documentation (added information about "account set" and sorted the list of settings because it was a bit too random).
Property mode set to `100644`
