+    \title Inter-Process Communication in Qt
+    \brief Inter-Process communication in Qt applications.
+
+    \ingroup frameworks-technologies
+
+    Qt provides several ways to implement Inter-Process Communication
+    (IPC) in Qt applications.
+
+    \section1 TCP/IP
+
+    The cross-platform \l{QtNetwork} module provides classes that make
+    network programming portable and easy. It offers high-level
+    classes (e.g., QNetworkAccessManager, QFtp) that communicate using
+    specific application-level protocols, and lower-level classes
+    (e.g., QTcpSocket, QTcpServer, QSslSocket) for implementing
+    protocols.
+
+    \section1 Shared Memory
+
+    The cross-platform shared memory class, QSharedMemory, provides
+    access to the operating system's shared memory implementation.
+    It allows safe access to shared memory segments by multiple threads
+    and processes. Additionally, QSystemSemaphore can be used to control
+    access to resources shared by the system, as well as to communicate
+    between processes.
+
+    \section1 D-Bus
+
+    The \l{QtDBus} module is a Unix-only library
+    you can use to implement IPC using the D-Bus protocol. It extends
+    Qt's \l{signalsandslots.html} {Signals and Slots} mechanism to the
+    IPC level, allowing a signal emitted by one process to be
+    connected to a slot in another process. This \l {Introduction to
+    D-Bus} page has detailed information on how to use the \l{QtDBus}
+    module.
+
+    \section1 Qt COmmunications Protocol (QCOP)
+
+    The QCopChannel class implements a protocol for transferring messages
+    between client processes across named channels. QCopChannel is
+    only available in \l{Qt for Embedded Linux}. Like the \l{QtDBus}
+    module, QCOP extends Qt's \l{Signals and Slots} mechanism to the
+    IPC level, allowing a signal emitted by one process to be
+    connected to a slot in another process, but unlike QtDBus, QCOP
+    does not depend on a third party library.
