dS )�DebconfaT A class that speaks the debconf protocol.
The simplest way to use this is as a context manager:
import debconf
with debconf.Debconf(run_frontend=True) as db:
print(db.get('debconf/frontend'))
Note that this will send the STOP command on exiting the context
manager, so you shouldn't expect to be able to use the same frontend
again after this. If you need to do that, then you should instantiate
the class directly instead:
import debconf
db = debconf.Debconf(run_frontend=True)
print(db.get('debconf/frontend'))
