+SUMMARY="Simplifies the usage of decorators for the average programmer"
+DESCRIPTION="The goal of the decorator module is to make it easy to define \
+signature-preserving function decorators and decorator factories.
+It also includes an implementation of multiple dispatch and other niceties \
+(please check the docs).
+It is released under a two-clauses BSD license, i.e. basically you can do \
+whatever you want with it but I am not responsible."
