  Thanks go out to the following people who have helped me debug and extend
sac to the pinnacle of perfection that it is. =)

Ian Harris
  - Found bug in the way sac releases logins when EOF is reached that made
    clipping not perform correctly (only for logins currently active).
  - Suggested extending -s and -e options to allow for more precision than
    just days. Thus: mm/dd/yy [hh:mm[:ss]] (to be implemented)

Jason Lavoie
  - Provided tacacs wtmp to implement -t option to support tacacs special
    wtmp format.

Ben Deptola
  - Suggested the -b option.

Scott Burch
  - Suggested -o option to support tacacs old wtmp format. Provided wtmp for
    testing.

Edward S. Marshall
  - Added functionality to the Makefile and FSSTND compliance.

Thomas Pawlikaniec
  - Got me to implement clipping finally.
  - Suggested --help option.
  - Made C code comments reflect reality.
  - Suggested -x option.
