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.
