 A hashref or arrayref of hashrefs defining the repositories used to find and fetch library tarballs (or zipballs etc.). These attributes are used to create C<Alien::Base::ModuleBuild::Repository> objects (or more likely, subclasses thereof). Which class is created is governed by the C<protocol> attribute and the C<alien_repository_class> property below. Available attributes are:
 
+=item alien_isolate_dynamic
+
+[version 0.005]
+
+If set to true, then dynamic libraries will be moved from the C<lib> directory to a separate C<dynamic> directory.  This makes them available for FFI modules (see L<FFI::Raw>), while preferring static libraries when creating XS extensions.
