/**
* @brief Generic DCOP interface for KDE instant messenger applications
*
* The interface has two parts:
* - methods to get information about IM-contacts, such as their reachability
* or their presence status (if the are online or away, etc)
* - methods to initiate communication with IM-contacts, e.g. sending messages
*
* @note If you are looking for a information about accessing application's
* that implement this interface, have a look at the KIMProxy class.
*
* Contacts are identified using unique identifier strings (UID) used by
* KABC, the KDE address book library.
* The UID generation is handled by TDEABC::Addressee so the your application
* will either have to access the address book or provide a possibility
* for associating a contact of your application with an entry of the address
* book.
*
* @note one omission of this interface is the lack of control over the range
* of values used for protocols' names.
*
* If you are implementing this interface, note that your application must
* have the following information in its desktop file, so that it can be
* identified as providing KIMIface at runtime:
* @code
* X-DCOP-ServiceName=<application-name>
* ServiceTypes=DCOP/InstantMessenger
* @endcode
* and the class implementing KIMIface must pass "KIMIface" to the DCOPObject constructor:
* @code
* // just need TQObject inheritance and TQ_OBJECT if you want signals and slots
* // no need to use K_DCOP macro again
*
* class MyIMIface : public TQObject, public KIMIface
* {
* TQ_OBJECT
* public:
* MyIMIface(TQObject* parent = 0, const char* name) :
* DCOPObject("KIMIface"), // <-- passing the interface name as required
* TQObject(parent, name) {}
* };
* @endcode
*
* The DCOP part of the interface needs to be processed by the DCOP IDL
* compiler. The KDE autotools framework will do this automatically, all
* you have to do is add kimiface.skel and kimiface.stub to the
* @c SOURCES list in your @c Makefile.am
*
* @see KIMProxy
* @see TDEABC::AddressBook
* @see TDEABC::Addressee
*
* @since 3.3
