Your ruby pplot can interface with any PPlot: it does not matter if it
is implemented in QT, cocoa or whatever.

type ./swigruby.sh to build pplot.so. You need to have SWIG installed
and ruby. (make sure you have $RUBYINCL defined)

For now a decent Ruby Painter class is not available, however,
you can link 'pplot_wrap.o' to your app if you want to embed ruby...
in that case you should not add require 'pplot' to your scripts, because the
pplot-ruby functions are already defined.



The best demo is in the qt directory. (look how to enable ruby in
qpplotdemo.pro). After building it with ruby enabled type
   qpplotdemo -ruby
and load an example script...
