# The default is 'name=0', meaning that the option is disabled by default.

# If the 'name:value' form is used, the value must be provided with the option (as '--name=myvalue').
# If the 'name:value=default' form is used, the option has the given default value even if not
# specified by the user.
# If the 'name:=value' form is used, the value is optional and the given value is used as the default

# Undocumented options are also supported by omitting the '=> description'.
# These options are not displayed with '--help' and can be useful for internal options or as aliases.
