-
-    \target qtconcurrent intro
-
-    The QtConcurrent namespace provides high-level APIs that make it
-    possible to write multi-threaded programs without using low-level
-    threading primitives such as mutexes, read-write locks, wait
-    conditions, or semaphores. Programs written with QtConcurrent
-    automatically adjust the number of threads used according to the
-    number of processor cores available. This means that applications
-    written today will continue to scale when deployed on multi-core
-    systems in the future.
-
-    QtConcurrent includes functional programming style APIs for
-    parallel list processing, including a MapReduce and FilterReduce
-    implementation for shared-memory (non-distributed) systems, and
-    classes for managing asynchronous computations in GUI
-    applications:
-
-    \list
-
-    \li QtConcurrent::map() applies a function to every item in a container,
-    modifying the items in-place.
-
-    \li QtConcurrent::mapped() is like map(), except that it returns a new
-    container with the modifications.
-
-    \li QtConcurrent::mappedReduced() is like mapped(), except that the
-    modified results are reduced or folded into a single result.
-
-    \li QtConcurrent::filter() removes all items from a container based on the
-    result of a filter function.
-
-    \li QtConcurrent::filtered() is like filter(), except that it returns a new
-    container with the filtered results.
-
-    \li QtConcurrent::filteredReduced() is like filtered(), except that the
-    filtered results are reduced or folded into a single result.
-
-    \li QtConcurrent::run() runs a function in another thread.
-
-    \li QFuture represents the result of an asynchronous computation.
-
-    \li QFutureIterator allows iterating through results available via QFuture.
-
-    \li QFutureWatcher allows monitoring a QFuture using signals-and-slots.
-
-    \li QFutureSynchronizer is a convenience class that automatically
-    synchronizes several QFutures.
-
-    \endlist
-
-    Qt Concurrent supports several STL-compatible container and iterator types,
-    but works best with Qt containers that have random-access iterators, such as
-    QList or QVector. The map and filter functions accept both containers and begin/end iterators.
-
-    STL Iterator support overview:
-
-    \table
-    \header
-        \li Iterator Type
-        \li Example classes
-        \li Support status
-    \row
-        \li Input Iterator
-        \li
-        \li Not Supported
-    \row
-        \li Output Iterator
-        \li
-        \li Not Supported
-    \row
-        \li Forward Iterator
-        \li std::slist
-        \li Supported
-    \row
-        \li Bidirectional Iterator
-        \li QLinkedList, std::list
-        \li Supported
-    \row
-        \li Random Access Iterator
-        \li QList, QVector, std::vector
-        \li Supported and Recommended
-    \endtable
-
-    Random access iterators can be faster in cases where Qt Concurrent is iterating
-    over a large number of lightweight items, since they allow skipping to any point
-    in the container. In addition, using random access iterators allows Qt Concurrent
-    to provide progress information trough QFuture::progressValue() and QFutureWatcher::
-    progressValueChanged().
-
-    The non in-place modifying functions such as mapped() and filtered() makes a
-    copy of the container when called. If you are using STL containers this copy operation
-    might take some time, in this case we recommend specifying the begin and end iterators
-    for the container instead.
