    through the normal distutils options.

    When using glob patterns, you can exclude certain module names explicitly

    For parallel compilation, set the 'nthreads' option to the number of
    concurrent builds.

    For a broad 'try to compile' mode that ignores compilation failures and
    simply excludes the failed extensions, pass 'exclude_failures=True'. Note

    be used without compilation.

    Compile a set of source modules into C/C++ files and return a list of distutils

    As module list, pass either a glob pattern, a list of glob patterns or a list of
    Extension objects.  The latter allows you to configure the extensions separately
    through the normal distutils options.

    When using glob patterns, you can exclude certain module names explicitly
    by passing them into the 'exclude' option.

    For parallel compilation, set the 'nthreads' option to the number of
    concurrent builds.

    For a broad 'try to compile' mode that ignores compilation failures and
    simply excludes the failed extensions, pass 'exclude_failures=True'. Note
    that this only really makes sense for compiling .py files which can also
    be used without compilation.

    Additional compilation options can be passed as keyword arguments.
