23 The "Alien::Role" namespace is intended for writing roles that can be
24 applied to Alien::Base to extend its functionality. You could of
25 course write subclasses that extend Alien::Base, but then you have to
26 either stick with just one subclass or deal with multiple inheritance!
27 It is recommended that you use Role::Tiny since it can be used on plain
28 old Perl classes which is good since Alien::Base doesn't use anything
29 fancy like Moose or Moo. There are two working examples that use this
30 technique that are worth checking out in the event you are interested:
31 Alien::Role::Dino and Alien::Role::Alt.
32
33 This class itself doesn't do anything, it just documents the technique.
