Some virtualenvs need to be installed on systems without compilers.  In particular, Talos systems don't have compilers or development libraries installed.  For these cases, we install packages that can fall back to a pure-python implementation when the compile fails.  Sadly, there's not much documentation about how this was done way-back-when, but the Twisted tarball was opened up, and two 'setup.py` files were edited to remove the extensions, then it was re-tarred and placed in this directory.  Newer Twisteds may not need this treatment.

Some virtualenvs need to be installed on systems without compilers.  In particular, Talos systems don't have compilers or development libraries installed.  For these cases, we install packages that can fall back to a pure-python implementation when the compile fails.  The tarball of Twisted-10.2.0 is *not* the one from pypi; that tarball was unpacked, ''conditionalExtensions'' was set to ''[]'' in both ''setup.py'' and ''twisted/topfiles/setup.py'', and a new tarball made with ''setup.py sdist'', and the result is in the python-packages directory.  Newer Twisteds may not need this treatment -- who knows.
