Extace Waveform Viewer
----------------------

   This is the extace waveform viewer. It plugs itself in as a EsounD
   monitor and samples and displays the output from the EsounD daemon.

   You will need EsounD and the GNU scientific library (gsl) or the
   FFTW (Fastest FFT in the West) library to build and run extace. 
   The FFT lib is preferred as its about 30% faster.  The configure
   script will default to fftw if both libs are found.
   
   The GNU scientific library can be found on alpha.gnu.org.

   The FFTW lib can be found on http://www.fftw.org/.

   The EsounD daemon 'esd' will need to be running as well.

   Currently there are no command line parameters. An options panel
   is avalailable to tune the speed, and 3D effects.

   NEW! The axis can be moved just by "dragging" then with the mouse.
   Just move close to the end of the trace, click and hold, and drag to taste.
   Don't go to fast or you'll loose the trace though.

   The sine.c is an example program to test extace with, just run

	./sine | esdcat

   The options button will allow you to change all sorts of variables
   such as: axis tilting, axis scroll speed, number of points in the display,
   decay control, and sensitivity.

   Enjoy!
