The module provides composable functors to implement scores via compile-time composition. Currently, there is support for distance based IMP::PairScore types generated from the IMP::scoring_function::DistanceScore and IMP::scoring_function::DistancePairScore. Angles and others can be added if desired. No functionality is exported to python. It can be done with some work, but it is not clear that it would be very useful. _Author(s)_: Daniel Russel _License_: [LGPL](http://www.gnu.org/licenses/old-licenses/lgpl-2.1.html) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. _Publications_: - See main IMP papers list.
