+
+Overview
+--------
+
+GpgMEpp is a C++ wrapper (or C++ bindings) for the GnuPG project's
+gpgme (GnuPG Made Easy) library, version 0.4.4 and later.
+
+It is fairly complete, with some minor things still missing (in
+particular, the key edit interface).
+
+The design principles of this library are as follows:
+
+1. A value-based interface (most clases are implicitly shared)
+2. Callbacks are replaced by C++ interfaces (classes with only
+   abstract methods).
+3. No exceptions are thrown
+4. There is (as yet) no explicit support for multi-threaded use
+   (other than what gpgme itself provides; most notably the
+   refcounting for implicit sharing is not thread-safe)
+5. To avoid binary incompatible interface changes, we make
+   extensive use of the d-pointer pattern and avoid virtual
+   methods; any polymorphism present is already provided by gpgme
+   itself, anyway (see e.g. Data). A notable exception of the
+   no-virtuals rule is the use of abstract classes to cover
+   C-callbacks.
+
+GpgMEpp was originally developed as part of the KDEPIM community
+in KDE 4 it was part of kdepimlibs/gpgme++ for KF5 Gpgmepp was
+renamed to KF5GpgMEpp and moved into it's own repository.
+
+Hacking
+-------
+GpgMEpp follows KDE Coding styles. See:
+https://techbase.kde.org/Policies/Frameworks_Coding_Style
+for more info.
+
+License
+-------
+
+This library is licensed under the GNU Library General Public
+License (LGPL), just as gpgme is. We feel that using a different
+license than the one gpgme itself uses doesn't make sense.

+/*! \file eventloopinteractor.h
+    \brief Abstract base class for gpgme's external event loop support
+
+    This class does most of the work involved with hooking GpgME++
+    up with external event loops, such as the GTK or Qt ones.
+
+    It actually provides two interfaces: An interface to the gpgme
+    IO Callback handling and one for gpgme events. The IO Callback
+    interface consists of the three methods \c actOn(), \c
+    registerWatcher() and \c unregisterWatcher(). The event
+    interface consists of the three methods \c nextTrustItemEvent(),
+    \c nextKeyEvent() and \c operationDoneEvent().
+
+    \sect General Usage
+
+    \c EventLoopInteractor is designed to be used as a
+    singleton. However, in order to make any use of it, you have to
+    subclass it and reimplement it's pure virtual methods (see
+    below). We suggest you keep the constructor protected and
+    provide a static \c instance() method that returns the single
+    instance. Alternatively, you can create an instance on the
+    stack, e.g. in \c main().
+
+    If you want \c EventLoopInteractor to manage a particular \c
+    Context, just call \c manage() on the \c Context. OTOH, if you
+    want to disable IO callbacks for a \c Context, use \c unmanage().
+
+    \sect IO Callback Interface
+
+    One part of this interface is represented by \c
+    registerWatcher() and \c unregisterWatcher(), both of which are
+    pure virtual. \c registerWatcher() should do anything necessary
+    to hook up watching of file descriptor \c fd for reading (\c dir
+    = \c Read) or writing (\c dir = Write) to the event loop you use
+    and return a tag identifying that particular watching process
+    uniquely. This could be the index into an array of objects you
+    use for that purpose or the address of such an object. E.g. in
+    Qt, you'd essentially just create a new \c QSocketNotifier:
+
+    \verbatim
+    void * registerWatcher( int fd, Direction dir ) {
+      return new QSocketNotifier( fd, dir == Read ? QSocketNotifier::Read : QSocketNotifier::Write );
+      // misses connecting to the activated() signal...
+    }
+    \endverbatim
+
+    which uses the address of the created object as unique tag. The
+    tag returned by \c registerWatcher is stored by \c
+    EventLoopInteractor and passed as argument to \c
+    unregisterWatcher(). So, in the picture above, you'd implement \c
+    unregisterWatcher() like this:
+
+    \verbatim
+    void unregisterWatcher( void * tag ) {
+      delete static_cast<QSocketNotifier*>( tag );
+    }
+    \endverbatim
+
+    The other part of the IO callback interface is \c actOn(), which
+    you should call if you receive notification from your event loop
+    about activity on file descriptor \c fd in direction \c dir. In
+    the picture above, you'd call this from the slot connected to
+    the socket notifier's \c activated() signal.
+
+    \note \c registerWatcher() as well as \c unregisterWatcher() may
+    be called from within \c actOn(), so be careful with
+    e.g. locking in threaded environments and keep in mind that the
+    object you used to find the \c fd and \c dir fo the \c actOn()
+    call might be deleted when \c actOn() returns!
+
+    \sect Event Handler Interface

+Overview
+--------
+QGpgme provides Qt API bindings around Gpgmepp. It depends on Gpgmepp.

+Hacking
+-------
+QGpgME comes from a KDE background. As such it does not use
+GNU Coding styles but KDE Coding styles. See:
