Dependencies: mpicxx python-netcdf python-mpi4py Running make will create a shared library called lib/libmapper.so Copy this library together with py/remap.py in one directory, and from there call python remap.py to see usage information. Memory debugging: -DDEBUG -DAUTO_LEAK_FIX The latter tries to fix memory leaks automatically through reference counting, otherwise it reports the memory leaks only.
