How to install tkpiechart as a Tcl package:

First, you must install stooop version 3.4 or above as a package (do
not forget to also install the switched class package). If you do not
have the stooop extension yet, get it from
http://www.mygale.org/~jfontain/,
ftp://ftp.neosoft.com/pub/tcl/incoming/ or
ftp://ftp.neosoft.com/pub/tcl/sorted/devel/

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 (the
default), 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-4.0/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 3.4
namespace import stooop::*
package require switched 1.4
package require tkpiechart 4.0
