     NAME
          twinkle - twinkle stars on the screen

     SYNOPSIS
          /usr/games/twinkle [-] [+] [s save]] [density1 [density2]]

     DESCRIPTION
          twinkle causes a specified density of ``stars'' to twinkle
          on the screen.

     FLAG OPTIONS
          The following flag options are available;

          -    Print out the present screen density (the percentage of
               the screen that will be filled with stars) in the
               lower-left corner of the screen.  This number changes
               as stars go on and off.

          +    Do not ``randomize'' before starting.  The screen
               starts out completely blank and stars are added, bit by
               bit.  In this case, the density rises beyond the speci-
               fied density, then falls to the required percentage.

          s    Save binary density on file save, in case you want to
               see the density curve that a particular density specif-
               ication produced during the life of the show.

          density
               If density is not specified, density is .5 (50% of the
               screen is filled with stars).
               If only density1 is given, density is 1/density1
               If both density1 and density2 are given, density is the
               resultant of density1/(density1+density2).

     EXAMPLES
          The command

             twinkle -+ 2 6

          would start from a blank screen and twinkle stars to a final
          density of 2/8, or 25%.  The densities would be shown in the
          lower-left corner, as a three-place decimal.
