16	History:
17
18	Modified by cmetz for OPIE 2.3. Removed unneeded debug message.
19	Modified by cmetz for OPIE 2.2. Use FUNCTION definition et al.
20               Fixed include order. Make everything static. Ifdef around
21               some headers.
22        Modified at NRL for OPIE 2.1. Substitute @@KEY_FILE@@. Re-write in
23	       C.
24        Modified at NRL for OPIE 2.01. Remove hard-coded paths for grep and
25               awk and let PATH take care of it. Substitute for Makefile
26               variables $(EXISTS) and $(KEY_FILE). Only compute $WHO if
27               there's a key file. Got rid of grep since awk can do the job
28               itself.
29	Modified at NRL for OPIE 2.0.
30	Written at Bellcore for the S/Key Version 1 software distribution
