 \class CaSoftwareRegistry.

 \brief This class provides access to USIF provided data and converting

 them from Symbian to Qt types.

 CaSoftwareRegistry class provides a factory method which returns smart pointer

 to CaSoftwareRegistry instnce to ensure

 automatical memory cleanup once the reference count drops to 0.

 \code

 QSharedPointer<CaSoftwareRegistry> service = CaSoftwareRegistry::create();

 \endcode

 Subsequent calls to CaSoftwareRegistry::create() may return pointers to different

 instances. It is a case when between the calls instance counter of the created

 object dropped to 0 and it was deleted.

 */

/*! \typedef typedef QHash<QString, QString> DetailMap;

 * Defines map type for component details.

 */

 \var CaSoftwareRegistryPrivate::m_q

 Points to the CaSoftwareRegistry instance that uses this private implementation.
