29    NAME
30	add_recip, madd_recip - add recipients to recipient list
31
32    SYNOPSIS
33	int add_recip(reciplist *plist, char *name, int checkdups)
34	int madd_recip(reciplist *plist, char *name, int checkdups)
35
36    DESCRIPTION
37	add_recip() adds the name to the recipient linked list.
38	If checkdups is set, it first checks to make certain that
39	the name is not in the list.
40
41	madd_recips() is given a list of names separated by white
42	space. Each name is split off and passed to add_recips.
