Copyright and License Terms
OWTChart is Open Source, which
means that it can be used freely, for personnal or commercial application,
as long as the authors' Copyright and Distribution terms are respected.  It is based on the GDChart
library, which in turn uses Boutell.com's
GD (GifDraw) library, so this means 3 sets of Copyright and Distribution
terms to follow. 
The application part of OWTChart was developed by Daniel Morissette (danmo@videotron.ca),
and part of it was done under contract with Health Canada. It is
covered by the following Copyright and Distribution terms:
