This is a Perl base class and framework for creating Alien distributions. The goal of the project is to make things as simple and easy as possible for both developers and users of Alien modules. Alien is a Perl name space for defining dependencies in CPAN for libraries and tools which are not "native" to CPAN. Alien modules will typically use the system libraries if they are available, or download the latest version from the internet and build them from source code. These libraries can then be used by other Perl modules, usually modules that are implemented with XS or FFI.  |  http://search.cpan.org/dist/Alien-Base-ModuleBuild/
