Module mod_sslcompat - SSL backward compatibility

> # Module mod_sslcompat
> SSL backward compatibility

> ## Summary

> This module provides backward compatiblity to old/other SSL modules by providing configuration directive stubs which map old directives to mod_ssl's directives. Currently stubs for Apache-SSL and Sioux configuration directives are provided.

> ## Installation

> This module is not compiled in by default. To enable this module you have to configure Apache via the following command:

> >     $ ./configure ... --enable-module=sslcompat
