! This is a template for adding a package-dependent implemetnation of
! the I/O API.  You can use the name xxx since that is already set up
! as a placeholder in module_io.F, md_calls.m4, and the Registry, or
! you can change the name here and in those other places.  For additional
! information on adding a package to WRF, see the latest version of the
