def rollup(self,rollupName,kwargs):
self.do_command("<STR_LIT>", [rollupName,kwargs,])<EOL>
Executes a command rollup, which is a series of commands with a unique
name, and optionally arguments that control the generation of the set of
commands. If any one of the rolled-up commands fails, the rollup is
considered to have failed. Rollups may also contain nested rollups.

'rollupName' is the name of the rollup command
'kwargs' is keyword arguments string that influences how the                    rollup expands into commands
