    platform

      Hash reference. Contains information about the platform beyond just
      $^O.

      platform.compiler_type

	Refers to the type of flags that the compiler accepts. May be
	expanded in the future, but for now, will be one of:

	microsoft

	  On Windows when using Microsoft Visual C++

	unix

	  Virtually everything else, including gcc on windows.

	The main difference is that with Visual C++ -LIBPATH should be used

	Contains a non-negative integer of available (possibly virtual)
	CPUs on the system. This can be used by build plugins to build in
	parallel. The environment variable ALIEN_CPU_COUNT can be set to
	override the CPU count.

      platform.cpu.arch.name

	Contains a normalized name for the architecture of the current
	Perl. This can be used by fetch plugins to determine which binary
	packages to download. The value may be one of the following, but
	this list will be expanded as needed.

	armel

	  32-bit ARM soft-float

	armhf

	  32-bit ARM hard-float

	aarch64

The detection logic should be done by the installer code (L<alienfile>
and L<Alien::Build>) and saved into runtime properties (see
L<Alien::Build/runtime_prop>).  And as much as
possible the runtime should be implemented in the base class (L<Alien::Base>).
Where reasonable, the base class should be expanded to meet the needs
of this arrangement.

=head3 when downloading a package grab the latest version

If the maintainer of an L<Alien> disappears for a while, and if the
version downloaded during a "share" install is hardcoded in the
L<alienfile>, it can be problematic for end-users.

There are exceptions, of course, in particular when a package provides
a very unstable interface from version to version it makes sense
