DESCRIPTION

       Draws a stick-man juggling various collections of objects.


OPTIONS

       -display host:display.screen
              X11 display to use.  Overrides DISPLAY environment variable.

       -root  Draw on the root window.

       -window
              Draw on a newly-created X window.  This is the default.

       -mono  Draw in monochrome.

       -install  |  -noinstall
              Turn on/off installing colormap.

       -visual visual
              Specify which visual to use.  Legal values are  the  name  of  a
              visual  class,  or  the id number (decimal or hex) of a specific
              visual.

       -window-id id
              Draw on an already existing X window.

       -pattern "pattern"
              Specify juggling pattern in annotated  site-swap  notation.   In
              site-swap  notation, the "height" of each throw is given.  E.g.,
              "3" is the height needed to juggle a 3-Cascade.  Note that these
              sequences need to be chosen carefully, to avoid collisions.

              Annotations indicate relative hand movements or tricks:

              -   Inside throw (default)
              +   Outside throw
              =   Cross Throw
              &   Cross Catch
              x   Cross Throw and Catch
              _   Bounce

       -pattern "[pattern]"
              Specify juggling pattern in annotated Adam notation.  Adam nota-
              tion is a little harder to visualize.  Each integer n represents
              a cyclic permutation of (0...n).  The equivalent site-swap value
              is determined by calculating how many  of  the  permutations  it
              takes  to  get back to the identity.  The largest number used is
              the same as the number of objects in the pattern.  The advantage
              of  Adam notation is that these sequences do not need to be cho-
              sen carefully, since all  possible  sequences  are  juggle-able.
              Annotations are the same as in site-swap notation.

              For example, both of these describe a 3-Shower:

              -pattern "+5 1"

              -pattern "[+3 1]"

              For further examples, see the portfolio list in the source code.

       -tail number
              Minimum Trail Length.  0 - 100.  Default: 0.  Objects may  over-
              ride this, for example flaming torches always leave a trail.

       -real | -no-real
              Turn on/off real-time juggling.  Deprecated.  There should be no
              need to turn off  real-time  juggling,  even  on  slow  systems.
              Adjust speed using -count above.

       -describe | -no-describe
              Turn on/off pattern descriptions.

       -balls | -no-balls
              Turn on/off Balls.

       -clubs | -no-clubs
              Turn on/off Clubs.

       -torches | -no-torches
              Turn on/off Flaming Torches.

       -knives | -no-knives
              Turn on/off Knives.

       -rings | -no-rings
              Turn on/off Rings.

       -bballs | -no-bballs
              Turn on/off Bowling Balls.

       -count number
              Speed.  50  - 1000.  Default: 200.  This determines the expected
              time interval between a throw and the next catch,  in  millisec-
              onds.

       -cycles number
              Performance  Length.  50  -  1000.  Default: 1000.  Setting this
              smaller will force the juggler to switch patterns (and  objects)
              more often.

       -delay delay
              Additional  delay  between  frames,  in  microseconds.  Default:
              10000.  Deprecated.  Adjust speed using -count.

       -ncolors ncolors
              Maximum number of colors to use.  Default: 32.


ENVIRONMENT

       DISPLAY
              to get the default host and display number.

       XENVIRONMENT
              to get the name of a resource file  that  overrides  the  global
              resources stored in the RESOURCE_MANAGER property.
