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.
|
|
Written at Bellcore for the S/Key Version 1 software distribution
