The setup.py build and install commands run a number of subcommands, including build_ext, which runs SWIG to generate openbabel.py, and build_py, which copies openbabel.py and other python sources to the build directory. The default ordering is for build_py to be run before build_ext, causing errors as build_py attempts to copy openbabel.py before it exists. This change ensures build_ext is always run first at the start of both the build and install commands.
Open Babel Python Bindings
==========================
This is a Python interface to the Open Babel chemistry library.
Open Babel is a chemical toolbox designed to speak the many languages
of chemical data. It's an open, collaborative project allowing anyone
to search, convert, analyze, or store data from molecular modeling,
chemistry, solid-state materials, biochemistry, or related areas.
For installation instructions, tutorials and examples, please visit the
`Open Babel website <http://openbabel.org/wiki/Python>`_.
This package provides two Python modules that can be used to access the
functionality of Open Babel toolkit:
- The `openbabel <http://openbabel.org/docs/dev/UseTheLibrary/PythonDoc.html>`_
module: A wrapper that is automatically generated using the SWIG package
and provides access to almost all of the Open Babel interfaces via Python,
including the base classes OBMol, OBAtom, OBBond, and OBResidue, as well
as the conversion framework OBConversion.
- The `pybel <http://openbabel.org/docs/dev/UseTheLibrary/Python_Pybel.html>`_
module: A lightweight wrapper around the classes and methods in the
openbabel module. Pybel provides more convenient and Pythonic ways to
access the Open Babel toolkit.
