+  \class QContactAction
+  \brief The QContactAction class provides an interface for performing an
+  action on a QContact or QContactDetail.
+  \ingroup contacts-main
+  \ingroup contacts-actions
+
+  An action is anything that can be performed on a contact, or a detail of a contact.  An example
+  of an action might be "Send Email" or "Dial" or "Plot Navigation Route".  One action may be
+  implemented by multiple vendors, and indeed one vendor may provide multiple implementations of
+  the same action.  The name of an action identifies its semantics, while its implementation version
+  distinguishes it from other implementations of the action by the same vendor.
+
+  Invocation of an action is asynchronous; at some stage after calling \l invokeAction() the
+  action instance will emit the \l stateChanged() signal.  Any results of the action may be retrieved
+  by calling \l results(), and as results become available the action will emit \l resultsAvailable().
+
+  Each instance of a QContactAction is created by a \l QContactActionFactory when
+  \l QContactActionFactory::instance() is called; the caller takes ownership of the action instance.
+ 
+  \sa QContactActionFactory, QContactActionFilter
+ */
+
+/*!
+  \fn QContactAction::~QContactAction()
+  Clears any memory in use by this instance of the action implementation
+ */
+
+/*!
+  \fn QContactAction::actionDescriptor() const
+  Returns the descriptor which uniquely identifies this action implementation.  A descriptor
+  consists of an action name, a vendor name and an implementation version.
+  The name of the action identifies the action provided; different implementations of an action
+  with the same name must provide the same functionality, but may differ in implementation semantics.
+  Hence, the action name includes the major version of the interface definition implemented.
+  The vendor name is the identification string of the vendor which has provided this implementation.
+  The implementation version is the (minor) version of the implementation, and is vendor-specific.

+  Some actions may require other information to be available in order to complete successfully; in that case,
+  the action will also inspect the given \a contact to ensure that it contains the information required.
+  If the contact contains the required information, the function will return true; otherwise, returns false.

+  eligible detail saved in the contact if the given \a detail is empty, with the given \a parameters specified.
+  At some point after invocation, one or more \l resultsAvailable() signals will be emitted by the action instance.
+  The results of the action (if any) may be retrieved by calling \l results().
+  When the state of the action changes, the \l stateChanged() signal will be emitted.
+
+  Returns true if the action was invoked successfully, otherwise false.  The return value says nothing
+  about whether the action which was invoked was successful or not, only whether it was initiated or
