This module contains the eABF/DRR method to do free energy calculation or enhance sampling along CVs.
This module is not installed by default and depends on the boost serialization module. Please make sure the boost serialization library is compiled and installed in your system before trying to compile this module. Add '--enable-modules=drr --enable-boost_serialization' to your './configure' command when building PLUMED to enable these features.
Please read drr_tool and DRR for more information.
