configuration variables available depend heavily on the platform and
configuration. The values may be retrieved using
get_config_var(name), and the list of variables is available via
get_config_vars().keys(). Additional convenience functions are also
available.

Assume the executable is in the build directory. The
pyconfig.h file should be in the same directory. Since
the build directory may not be the source directory,
use "srcdir" from the makefile to find the "Include"
directory.

directory from the config vars. Useful when
cross-compiling, since the config vars may come from
the host
platform Python installation, while the current Python
executable is from the build platform installation.

everything needed to build extensions and install both pure modules and

With arguments, return a list of values that result from looking up
each argument in the configuration variable dictionary.
