29 /*----- Revision history --------------------------------------------------*
32 * Revision 1.5 2003/10/12 00:14:55 mdw
33 * Major overhaul. Now uses DSA signatures rather than the bogus symmetric
34 * encrypt-and-hope thing. Integrated with mLib and Catacomb.
36 * Revision 1.4 1998/01/12 16:46:38 mdw
39 * Revision 1.3 1997/08/20 16:25:08 mdw
40 * Rename `userdb_reinit' to `userdb_end' for more sensible restart.
42 * Revision 1.2 1997/08/04 10:24:26 mdw
43 * Sources placed under CVS control.
