Command

This class provides a command-line interface to generate the SQL statements required to reset all tables in a database to their initial post-installation state. It supports targeting specific databases via an optional argument and ensures the resulting output is wrapped in a transaction. The class utilizes database-specific utilities to identify and format the necessary flush operations.

help	string	Returns a list of the SQL statements required to return all tables in the database to the state they were in just after they were installed.
