dS )� StateFileaf A metadata file for recording system state which can
be backed up and later restored.
StateFile gets reloaded every time to prevent loss of information
recorded by child processes. But we do not solve concurrency
because there is no need for it right now.
The format is something like:
[httpd]
running=True
enabled=False
c C s" t j�||�| _i | _| �� dS )a� Create a StateFile object, loading from @path.
The dictionary @modules, a member of the returned object,
is where the state can be modified. @modules is indexed
using a module name to return another dictionary containing
key/value pairs with the saved state of that module.
The keys in these latter dictionaries are arbitrary strings
and the values may either be strings or booleans.
