10: * newsgroup(lookfor, mapped,direct)
11: *
12: * This routine looks in the file specified by NEWSALIAS
13: * for a correspondence between the notesfile name supplied
14: * and a news(1) newsgroup.
15: * The resultant match is placed where the second parameter points.
16: * In the event of no match, the same name is passed back.
17: *
18: * direct gives us the direction of mapping:
19: * NFNEWS says that lookfor is a notesfile and we find a newsgroup
20: * NEWSNF says that lookfor is a newsgroup and we find a nf
21: * in both cases lookfor is the input and mapped is the output
