[chimera-dev] Running Chimera through Python script

[Eric Pettersen]

Hi Evan,
	That code only works in the context of Chimera’s Python interpreter, not a generic Python interpreter.  So like it says in the example, “to execute the script, either open the script file with the File→Open menu item or with the open command”.  
	Third parties have developed modules to allow Chimera modules to be used in standard Python interpreters.  One such package is pychimera, <https://pypi.python.org/pypi/pychimera/0.2.0> which can be installed via pypi.
	Chimera only supports Python2.  ChimeraX uses Python3.
