+This module encapsulates the exporting of sugar functions in a
+C<Mouse.pm>-like manner. It does this by building custom C<import>,
+C<unimport> methods for your module, based on a spec you provide.
 
 Note that C<Mouse::Exporter> does not provide the C<with_meta> option,
 but you can easily get the metaclass by C<< caller->meta >> as L</SYNOPSIS> shows.
