[ANNOUNCE] Twenty-third release of PythonCAD now available

["Art Haas" <ahaas airmail net>]

I'm pleased to announce the twenty-third development release of PythonCAD,
a CAD package for open-source software users. As the name implies,
PythonCAD is written entirely in Python. The goal of this project is
to create a fully scriptable drafting program that will match and eventually
exceed features found in commercial CAD software. PythonCAD is released
under the GNU Public License (GPL).

PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0
based, and uses the PyGTK module for interfacing to GTK. The design of
PythonCAD is built around the idea of separating the interface
from the back end as much as possible. By doing this, it is hoped
that both GNOME and KDE interfaces can be added to PythonCAD through
usage of the appropriate Python module. Addition of other PythonCAD 
interfaces will depend on the availability of a Python module for that
particular interface and developer interest and action.

The twenty-third release contains a several bug fixes, the largest of
which is the correct restoration of dimension string text properties when
the deletion of a dimension is undone. Another fix included in this release
is the removal of some deprecated constants flagged by the 2.6 PyGTK
release when they are encountered. This release also features the
beginnings of the scripting enhancements planned for PythonCAD. The
evaluation of user-entered expressions is now more powerful by utilizing
Python's exec keyword and invoking the eval() command with an argument
storing variables to be utilized during expression evaluation. More
enhancements and improvements in expression evaluation and overall
scriptability will appear in future releases.
