Boot doesn't allow to pass arguments to a task bypassing its own CLI framework.
Because of this, the example uses a single -a option that takes a string with
options for Omniconf.
Navigate to this directory and execute:
OPTION_FROM_SET=foo boot run -a '--required-option bar'
Experiment with configuration to change it, break it etc.
Run help to see all options:
boot run -a '--help'
