Welcome to the PostScript plt demonstration!
This script runs 'plt' to display the figures included in the plt Tutorial
and Cookbook. This version of the demo generates PostScript figures and
displays them using GhostScript (via lwcat -gv).
In order to run this demonstration successfully, both 'plt' and GhostScript
must have been installed first. Each example is shown in a GhostScript
(gv or gsview) window. Exit from GhostScript when you have finished with each
example in order to see the next example (you can do this by typing 'q' into
the gv window, or <alt>f x in the gsview window).
The most recent version of plt is always available from PhysioNet
(http://www.physionet.org/), and the most recent version of GhostScript is
always available from http://ghostscript.com/.
