JChemPaint [KRA00] is an editor for 2D Molecular Structures,
like this one here We believe that scientific software, especially when its development was
publically funded, should be free. As the GNU (http://www.gnu.org) people put it: Free Software
is a matter of liberty, not price. To understand the concept, you should
think of 'free speech', not 'free beer.' ". Everyone can participate in the development of the program. Everyone can
download and change the source code, provided that he makes the changes
publicly available again, according to the GNU General Public License (GPL)
or GNU Lesser General Public License (LGPL), depending on the classes
which have been changed. It also ensures that a scientist, who needs a standard piece of software
like a structure editor as a helper application in her new program,
does not have to reinvent the wheel over and over again because all the
structure editors that have been written before are now proprietory software.
If there is a free structure editor, she can focus on the real science..
JChemPaint is intended to be complementary to JMol(http://www.openscience.org/jmol),
a visualisation and analysis tool for 3D molecular structures, which is,
like JChemPaint, developed by an international team of opensource programmers.
In at least three aspects JChemPaint is different from other programs of this sort:
JChemPaint, currently in release 2.0, supports:
