New Revision: 29017

URL: http://svn.digium.com/view/asterisk?rev=29017&view=rev
Log:
- add a UserEvent action that allows a manager client to "broadcast" an event
  to all connected manager clients
- update the UserEvent application to use the application argument parsing
  macros and to allow headers to be specified as pipe delimeted arguments
  (issue #5324, original patch by outtolunc, committed patch by Corydon)

+* app_userevent has been modified to always send Event: UserEvent with the
+  additional header UserEvent: <userspec>.  Also, the Channel and UniqueID
+  headers are not automatically sent, unless you specify them as separate
+  arguments.  Please see the application help for the new syntax.

 Variables:
 
 * The builtin variables ${CALLERID}, ${CALLERIDNAME}, ${CALLERIDNUM},
