Re: [Visualpython-users] License

I guess the confusion is that in the case of the Windows and Mac installers,
the modules are included in the VPython installers. On the Linux download
page at vpython.org you will see "In support of the 3D text object, you will
need to install the font-handling modules FontTools, ttfquery (version 1.0.4
or later), and Polygon (all available from pypi.python.org), for which the
following conditions apply:" followed by an extract from the Visual
license.

Also, in INSTALL.txt included in the Visual tarball you will see "For Visual
5.3 and later, you need the Python modules FontTools, ttfquery, and
Polygon. Be sure to get ttfquery 1.0.4 or later." This is followed by the
specific information about Polygon.

If you don't install these components on Linux the new text object won't
work.

Hope this helps.
