-======================================================================
-		Implementation details for developers
-----------------------------------------------------------------------
-
-Python and python modules can now be built as shared libraries on AIX
-as usual.
-
-AIX shared libraries require that an "export" and "import" file be
-provided at compile time to list all extern symbols which may be
-shared between modules.  The "export" file (named python.exp) for the
-modules and the libraries that belong to the Python core is created by
-the "makexp_aix" script before performing the link of the python
-binary. It lists all global symbols (exported during the link) of the
-modules and the libraries that make up the python executable.
-
-When shared library modules (.so files) are made, a second shell
-script is invoked.  This script is named "ld_so_aix" and is also
-provided with the distribution in the Modules subdirectory.  This
-script acts as an "ld" wrapper which hides the explicit management of
-"export" and "import" files; it adds the appropriate arguments (in the
-appropriate order) to the link command that creates the shared module.
-Among other things, it specifies that the "python.exp" file is an
-"import" file for the shared module.
-
-This mechanism should be transparent.
