| 21 | # @Program Functionality: |
---|
| 22 | # Depending on the selected installation environment (locally or on the |
---|
| 23 | # ECMWF server ecgate or cca) the program extracts the commandline |
---|
| 24 | # arguments and the CONTROL file parameter and prepares the corresponding |
---|
| 25 | # environment. The necessary files are collected in a tar-ball and placed |
---|
| 26 | # at the target location. There its untared, the environment variables will |
---|
| 27 | # be set and the Fortran code will be compiled. If the ECMWF environment is |
---|
| 28 | # selected a job script is prepared and submitted for the remaining |
---|
| 29 | # configurations after putting the tar-ball to the target ECMWF server. |
