The file "demo.tcl" contains a Tcl script to run the demo as see during the
Tcl/Tk 2015 conference presentation.

In order to run the demo you will need to have TclRAL installed.  TclRAL is a
binary extension and precompiled packages for the major platforms may be found
at:

http://repos.modelrealization.com/cgi-bin/fossil/tclral/wiki?name=Downloads

or

http://chiselapp.com/user/mangoa01/repository/tclral/wiki?name=Downloads

The package downloads from these sites is suitable to place directly into
a local teapot, e.g.

$ teapot install package-tclral-0.11.8-linux-glibc2.19-x86_64.zip

where the package name will vary depending upon your platform.

Alternatively, the package zip file may be expanded in your module path or
along your package load path.

Once TclRAL is installed, it is a simple matter of invoking demo.tcl. Note for
Windows users, the files here are in Unix/Mac LF format and you may have to do
some minor conversions or otherwise figure out how to invoke the script in the
Windows environment.
