=head1 SYNOPSIS

Command line tool:

 use Alien::7zip;
 use Env qw( @PATH );

 unshift @PATH, Alien::7zip->bin_dir;
 system "@{[ Alien::7zip->exe ]}";

=head1 DESCRIPTION

This distribution provides 7-Zip so that it can be used by other
Perl distributions that are on CPAN.  It does this by first trying to
detect an existing install of 7-Zip on your system.  If found it
will use that.  If it cannot be found, the source code will be downloaded
from the internet and it will be installed in a private share location
for the use of other modules.
