How to install tkpiechart as a Tcl package:

First, you must install stooop version 3.7 or above as a package (do
not forget to also install the included switched class package). If
you do not have the stooop extension yet, get it from any of the
following locations:

  http://jfontain.free.fr/
  somewhere in ftp://ftp.neosoft.com/pub/tcl/

Once the stooop package is working and installed, you are ready to
install tkpiechart as a package. Choose a directory where the package
should be installed (for example /usr/local/lib/tkpiechart), but you
may choose another: look at the pkg_mkIndex manual page for more
information (well look at it any case :-)).

Now type (from the tkpiechart installation directory):

$ mkdir /usr/local/lib/tkpiechart
$ instapkg.tcl /usr/local/lib/tkpiechart

To test if it works:

$ cd ..
$ wish tkpiechart-5.x/demo

should display the tkpiechart demonstration applet.

If you want to use tkpiechart as a package in your application, invoke
the following 2 instructions before you create any pie:

package require stooop 3.7
namespace import stooop::*
package require switched 1.4
package require tkpiechart 5.4
