JChemPaint [KRA00] is an editor for 2D
Molecular Structures, like this one here
We believe that scientific software, especially when its development was
publicly 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 propriety 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 open source programmers.
In at least three aspects JChemPaint is different from other programs of
this sort:
JChemPaint in its currently release supports:
