- Implements the Distutils 'build_clib' command, to build a C/C++ library
- that is included in the module distribution and needed by an extension
- module."""

- # XXX this module has *lots* of code ripped-off quite transparently from
- # build_ext.py -- not surprisingly really, as the work required to build
- # a static library from a collection of C source files is not really all
- # that different from what's required to build a shared object file from
- # a collection of C source files. Nevertheless, I haven't done the
- # necessary refactoring to account for the overlap in code between the
- # two modules, mainly because a number of subtle details changed in the
- # cut 'n paste. Sigh.
