+metaclass and export the moose declarators (C<has>, C<with>, C<extends>,...).
+Here is an example:
+
+ package MyFramework;
+ use Moose;
+
+ sub import {
+ my $CALLER = caller();
+
+ strict->import;
+ warnings->import;
+
+ # we should never export to main
+ return if $CALLER eq 'main';
+ Moose::init_meta( $CALLER, 'MyFramework::Base' );
+ Moose->import({into => $CALLER});
+
+ # Do my custom framework stuff
+
+ return 1;
+ }
+
+=head2 B<import>
+
+Moose's C<import> method supports the L<Sub::Exporter> form of C<{into =E<gt> $pkg}>
+and C<{into_level =E<gt> 1}>
+
+=head2 B<init_meta ($class, $baseclass, $metaclass)>
+
+Moose does some boot strapping: it creates a metaclass object for your class,
+and then injects a C<meta> accessor into your class to retrieve it. Then it
+sets your baseclass to Moose::Object or the value you pass in unless you already
+have one. This is all done via C<init_meta> which takes the name of your class
+and optionally a baseclass and a metaclass as arguments.

F<t/014_override_augment_inner_super.t> for an example.
