-=head1 METHODS
+=head2 Use 'traits' instead of 'metaclass'
 
-These methods are of little use to most users, they are used interally 
-within L<MooseX::Getopt>.
+You should rarely need to explicitly set the attribute metaclass. It is much
+preferred to simply provide a trait (a role applied to the attribute
+metaclass), which allows other code to futher modify the attribute by applying
+additional roles.
 
-=over 4
+Therefore, you should first try to do this:
 
-=item B<cmd_flag>
+  has 'foo' => (traits => ['Getopt'], cmd_flag => 'f');
 
-Changes the commandline flag to be this value, instead of the default,
-which is the same as the attribute name.
+=head2 Custom Metaclass alias
 
-=item B<cmd_aliases>
+This now takes advantage of the Moose 0.19 feature to support
+custom attribute metaclass aliases. This means you can also
+use this as the B<Getopt> alias, like so:
 
-Adds more aliases for this commandline flag, useful for short options
-and such.
