Define a list of map names which starts out empty and has names
appended to it as the names are generated.
E.g.:
tmp_rast = []
def cleanup():
for rast in tmp_rast:
grass.run_command("g.remove",
rast = rast,
quiet = True)
def main():
...
while ...:
next_rast = ...
tmp_rast.append(next_rast)
...
if __name__ == "__main__":
options, flags = grass.parser()
atexit.register(cleanup)
sys.exit(main())
