 145          standard. It is used, for example, by automatic firmware updates used

 198          This is generally the right thing to do, except when there
 199          are strict constraints with regards to the kernel size,
 200          like on embedded systems.
 201
 202          Use this option with care, as deselecting ancillary drivers which
 203          are, in fact, necessary will result in the lack of the needed
 204          functionality for your device (it may not tune or may not have
 205          the needed demodulators).
