setup.py

#!/usr/bin/env python

# This setup.py builds xylib as a python extension, which is experimental.
# The normal way of building xylib is using configure && make. Or cmake.
long_description="""\
xylib is a library for reading obscure file formats with data from
powder diffraction, spectroscopy and other experimental methods.
For the list of supported formats see https://github.com/wojdyr/xylib .

This module includes bindings to xylib and xylib itself.
The first two numbers in the version are the version of included xylib.

Prerequisites for building: SWIG and Boost libraries (headers only).
