History:
Modified by cmetz for OPIE 2.3. Removed unneeded debug message.
Modified by cmetz for OPIE 2.2. Use FUNCTION definition et al.
Fixed include order. Make everything static. Ifdef around
some headers.
Modified at NRL for OPIE 2.1. Substitute @@KEY_FILE@@. Re-write in
C.
Modified at NRL for OPIE 2.01. Remove hard-coded paths for grep and
awk and let PATH take care of it. Substitute for Makefile
variables $(EXISTS) and $(KEY_FILE). Only compute $WHO if
there's a key file. Got rid of grep since awk can do the job
itself.
Modified at NRL for OPIE 2.0.
