PyMOL's SourceForge README
Jason Vertrees
1 What is PyMOL?
PyMOL is an open-source molecular visualization system built on
an open-source foundation. That means you get free access to
source code--hence 'open source.' Schrodinger compiles and sells
ready-to-run binaries for Windows, Mac, and Linux
(http://pymol.org/buy).
2 Source Code
2.1 Packaged Source
You can download the latest release source package from
SourceForge. Just click on 'Files' from the top menu.
2.2 Pulling from Subversion
You can download the open-source code in the same manner as for
the past decade via SourceForge. Nothing has changed here, just
visit https://sourceforge.net/projects/pymol/develop and download
from the SVN repository. That link also allows you to see the
changes to the open-source project, under the 'What's Happening
Section.'
3 Legacy Builds
To support the PyMOL community, Schrodinger provides access to
some PyMOL legacy builds at no-cost. A "PyMOL legacy build" is
any PyMOL build that is past its end-of-life (EOL) for support
and maintenance. PyMOL products' end-of-life information may be
found on our website (http://pymol.org/eol).
Legacy builds are not supported, in any way by Schrodinger: we
simply provide them as a convenience for our users. PyMOL-legacy
builds may be downloaded from PyMOL's SourceForge website
(https://sourceforge.net/projects/pymol/files). A mailing list
called "PyMOL-legacy" has been created to provide a central
location for users to discuss, and locate help for these
PyMOL-legacy builds.
