"""
Prepares the underlying BitBake system to be used via tinfoil.
This function must be called prior to calling any of the other
functions in the API.
NOTE: if you call prepare() you must absolutely call shutdown()
before your code terminates. You can use a "with" block to ensure
this happens e.g.
with bb.tinfoil.Tinfoil() as tinfoil:
tinfoil.prepare()
...
Parameters:
config_only: True to read only the configuration and not load
the cache / parse recipes. This is useful if you just
want to query the value of a variable at the global
level or you want to do anything else that doesn't
involve knowing anything about the recipes in the
current configuration. False loads the cache / parses
recipes.
config_params: optionally specify your own configuration
parameters. If not specified an instance of
TinfoilConfigParameters will be created internally.
quiet: quiet level controlling console output - equivalent
to bitbake's -q/--quiet option. Default of 0 gives
the same output level as normal bitbake execution.
extra_features: extra features to be added to the feature
set requested from the server. See
CookerFeatures._feature_list for possible
features.
