The C++ wrappers for the QuantLib-Python extension module are created
by means of SWIG (Simplified Wrapper and Interface Generator)
available from <http://www.swig.org/>; the latest version is suggested.
Both Python 2.7 and 3.x are supported.

Generating the wrappers is not required if you are using a distributed
tarball. If you're building from a Git checkout, instead, use the
command:

    python setup.py wrap

The commands to be issued for building, testing and installing the
wrappers are:

    python setup.py build
    python setup.py test
    python setup.py install

respectively.

The build step requires that the QuantLib headers and library can be
found by the compiler. On Unix-like platforms, this requires that
`quantlib-config` is in your path. On the Windows platform, instead,
it requires you to define a `QL_DIR` environment variable pointing to
your QuantLib directory (e.g., `C:\Lib\QuantLib`.)

The install step might require superuser privileges.
An alternate install location can be specified with the command:

    python setup.py install --prefix=/home/johndoe

The test suite is implemented on top of the PyUnit framework, which is
included in the Python standard library.
