  tclock - analog/digital clock for curses.
  If it gives you joy, then
  (a) I'm glad
  (b) you need to get out more :-)

This program is copyright Howard Jones, September 1994

  long as this copyright message remains intact, and any
  modifications are clearly marked as such. [In fact, if
  you modify it, I wouldn't mind the modifications back,
  especially if they add any nice features. A good one
  would be a precalc table for the 60 hand positions, so
  that the floating point stuff can be ditched. As I said,
  it was a 20 hackup minute job.]
