> There are currently two supported packages: ESMP and ESMPy.  Both of these packages have the same general functionality.  ESMP was a first prototype and ESMPy has a more Pythonic interface.  After the ESMF_620 release (expected in May), the ESMP package will be deprecated and the ESMPy package will enter a beta phase.
