* The LpConfig object is used to manipulate a configuration file.

* The format of the configuration file is a .ini like format:
* - sections are defined in []
* - each section contains a sequence of key=value pairs.
*
* Example:
* @code
* [sound]
* echocanceler=1
* playback_dev=ALSA: Default device
*
* [video]
* enabled=1
* @endcode
