plugins/notify.c

/* Rewritten by Etan Reisner <deryni@eden.rutgers.edu>
 *
 * Added config dialog
 * Added control over notification method
 * Added control over when to release notification
 *
 * Thanks to Carles Pina i Estany <carles@pinux.info>
 *   for count of new messages option
 */

/* if my flash messages patch gets merged in can use cnv->local
 * to notify on new messages also
