Starter Toolkit Library Functions. Edit the Makefile as
needed for your system, and then type "make"

Some facilities of the Starter Toolkit require the use of another
widget set which defined through the variable WSET in the Makefile.
If you leave this varibale undefined, the source will compile
and a library will be created but it will be missing some functions
such as begin_display(), setup_a_panel(), etc. The reduced library
will let you run only programs that use vis_window() or draw_window()
for creating the main application window.
