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.
