2.4 Distributing your extension modules

When distributing your extension modules in source form, make sure to include a `Setup` file. The `Setup` file should be named `Setup.in` in the distribution. The make file make file, `Makefile.pre.in`, will copy `Setup.in` to `Setup`. Distributing a `Setup.in` file makes it easy for people to customize the `Setup` file while keeping the original in `Setup.in`.

It is a good idea to include a copy of `Makefile.pre.in` for people who do not have a source distribution of Python.

Do not distribute a make file. People building your modules should use `Makefile.pre.in` to build their own make file. A `README` file included in the package should provide simple instructions to perform the build.

Work is being done to make building and installing Python extensions easier for all platforms; this work in likely to supplant the current approach at some point in the future.
