[REBOL] Re: comlib by Anton.... thanks!
From: moliad::gmail at: 26-Oct-2007 9:41
Hi Robert,
actually, Anton's examples where pretty easy to understand directly.
Although they depended on having MS Office installed (which I don't right
now).
I used it with winGraphViz.
here is my test script, the structure is taken from one of Anton's examples.
to run:
-just download and register wingraphviz (
http://wingraphviz.sourceforge.net/wingraphviz/setup.htm).
-get anton's comlib, and save the following in the comlib dir.
-just run the script.
