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