    Sets or gets the property values used as defaults for commands.

    set: fconfig.sh set is deprecated. Use "${TOOLS_SHORT_PATH}/fconfig" to configure
        properties. This script only works for reading values.

    default: Restores the given property to the default value, or unsets.
    list: Lists prop=value one per line.

    propname: One of the predefined properties: $(get-fuchsia-property-names)).
    value: if using setting, the value to set to the property. Otherwise ignored.
