+Libev comes with some simplistic wrapper classes for \*(C+ that mainly allow
+you to use some convinience methods to start/stop watchers and also change
+the callback model to a model using method callbacks on objects.
+.PP
+To use it,
+.PP
+.Vb 1

+(it is not installed by default). This automatically includes \fIev.h\fR
+and puts all of its definitions (many of them macros) into the global
+namespace. All \*(C+ specific things are put into the \f(CW\*(C`ev\*(C'\fR namespace.
+.PP
+It should support all the same embedding options as \fIev.h\fR, most notably
+\&\f(CW\*(C`EV_MULTIPLICITY\*(C'\fR.
+.PP
+Here is a list of things available in the \f(CW\*(C`ev\*(C'\fR namespace:
+.ie n .IP """ev::READ""\fR, \f(CW""ev::WRITE"" etc." 4
+.el .IP "\f(CWev::READ\fR, \f(CWev::WRITE\fR etc." 4
+.IX Item "ev::READ, ev::WRITE etc."
+These are just enum values with the same values as the \f(CW\*(C`EV_READ\*(C'\fR etc.
+macros from \fIev.h\fR.
+.ie n .IP """ev::tstamp""\fR, \f(CW""ev::now""" 4
+.el .IP "\f(CWev::tstamp\fR, \f(CWev::now\fR" 4
+.IX Item "ev::tstamp, ev::now"
+Aliases to the same types/functions as with the \f(CW\*(C`ev_\*(C'\fR prefix.
+.ie n .IP """ev::io""\fR, \f(CW""ev::timer""\fR, \f(CW""ev::periodic""\fR, \f(CW""ev::idle""\fR, \f(CW""ev::sig"" etc." 4

+.IX Item "ev::io, ev::timer, ev::periodic, ev::idle, ev::sig etc."
+For each \f(CW\*(C`ev_TYPE\*(C'\fR watcher in \fIev.h\fR there is a corresponding class of
+the same name in the \f(CW\*(C`ev\*(C'\fR namespace, with the exception of \f(CW\*(C`ev_signal\*(C'\fR
+which is called \f(CW\*(C`ev::sig\*(C'\fR to avoid clashes with the \f(CW\*(C`signal\*(C'\fR macro
+defines by many implementations.

+All of those classes have these methods:
+.RS 4
+.IP "ev::TYPE::TYPE (object *, object::method *)" 4
+.IX Item "ev::TYPE::TYPE (object *, object::method *)"
+.PD 0
+.IP "ev::TYPE::TYPE (object *, object::method *, struct ev_loop *)" 4
+.IX Item "ev::TYPE::TYPE (object *, object::method *, struct ev_loop *)"
+.IP "ev::TYPE::~TYPE" 4
+.IX Item "ev::TYPE::~TYPE"
+.PD
+The constructor takes a pointer to an object and a method pointer to
+the event handler callback to call in this class. The constructor calls
+\&\f(CW\*(C`ev_init\*(C'\fR for you, which means you have to call the \f(CW\*(C`set\*(C'\fR method
+before starting it. If you do not specify a loop then the constructor
+automatically associates the default loop with this watcher.
+.Sp
+The destructor automatically stops the watcher if it is active.
+.IP "w\->set (struct ev_loop *)" 4
+.IX Item "w->set (struct ev_loop *)"
+Associates a different \f(CW\*(C`struct ev_loop\*(C'\fR with this watcher. You can only
+do this when the watcher is inactive (and not pending either).
+.IP "w\->set ([args])" 4
+.IX Item "w->set ([args])"
+Basically the same as \f(CW\*(C`ev_TYPE_set\*(C'\fR, with the same args. Must be
+called at least once.  Unlike the C counterpart, an active watcher gets
+automatically stopped and restarted.
+.IP "w\->start ()" 4
+.IX Item "w->start ()"
+Starts the watcher. Note that there is no \f(CW\*(C`loop\*(C'\fR argument as the
+constructor already takes the loop.
+.IP "w\->stop ()" 4
+.IX Item "w->stop ()"
+Stops the watcher if it is active. Again, no \f(CW\*(C`loop\*(C'\fR argument.
+.ie n .IP "w\->again ()       ""ev::timer""\fR, \f(CW""ev::periodic"" only" 4
+.el .IP "w\->again ()       \f(CWev::timer\fR, \f(CWev::periodic\fR only" 4
+.IX Item "w->again ()       ev::timer, ev::periodic only"
+For \f(CW\*(C`ev::timer\*(C'\fR and \f(CW\*(C`ev::periodic\*(C'\fR, this invokes the corresponding
+\&\f(CW\*(C`ev_TYPE_again\*(C'\fR function.
+.ie n .IP "w\->sweep ()       ""ev::embed"" only" 4
+.el .IP "w\->sweep ()       \f(CWev::embed\fR only" 4
+.IX Item "w->sweep ()       ev::embed only"
+Invokes \f(CW\*(C`ev_embed_sweep\*(C'\fR.
