""" Build ``cytoolz`` with or without Cython.
By default, CyToolz will be built using Cython if available.
If Cython is not available, then the default C compiler will be used
to compile the distributed *.c files instead.
Pass "--cython" or "--with-cython" as a command line argument to setup.py to
force the project to build using Cython (and fail if Cython is unavailable).
Pass "--no-cython" or "--without-cython" to disable usage of Cython.
For convenience, developmental versions (with 'dev' in the version number)
automatically use Cython unless disabled via a command line argument.
To summarize differently, the rules are as follows (apply first applicable rule):
1. If `--no-cython` or `--without-cython` are used, then only build from `.*c` files.
2. If this is a dev version, then cythonize only the files that have changed.
3. If `--cython` or `--with-cython` are used, then force cythonize all files.
4. If no arguments are passed, then force cythonize all files if Cython is available,
else build from `*.c` files. This is default when installing via pip.
By forcing cythonization of all files (except in dev) if Cython is available,
we avoid the case where the generated `*.c` files are not forward-compatible.
