T21.nc (or equivalent if using a higher resolution--provide your own though), and randomly generates continents according to the user's desired number of landmasses and land fraction. It's much better at getting the land fraction right than the number of landmasses, since as they grow landmasses often merge. Also generates template topography (higher elevation at landmass center, no mountains), and writes SRA boundary condition files for land-sea mask and orography.
