We have gone to considerable efforts to make this release flexible in a way that a user tailors the standard source code for a given application, while simultaneously bringing the central code under svn source code management.

The new structure of ROMS allows user specific CPP definitions and analytical options to be set in a small number of separate standalone header files. Therefore, users no longer have to modify small blocks of code in one long file like was neccessary in previous versions of cppdefs.h and analylitical.F. This makes it easy to distribute the configuration for a specific application via a small number of source code related files plus the inputs (grid, forcing netcdf files), while allowing users of the application to keep current with central code improvements via svn. This also takes care of all licensing issues. You are free to include your own statement of your contributions in the files you distribute. The license and copyright statements by the ROMS developer group remain in the source code distributed at
