-    \class QCollator
-    \inmodule QtCore
-    \brief The QCollator class compares strings according to a localized collation algorithm.
-
-    \since 5.2
-
-    \reentrant
-    \ingroup i18n
-    \ingroup string-processing
-    \ingroup shared
-
-    QCollator is initialized with a QLocale and an optional collation strategy.
-    It tries to initialize the collator with the specified values. The collator
-    can then be used to compare and sort strings in a locale dependent fashion.
-
-    A QCollator object can be used together with template based sorting
-    algorithms such as std::sort to sort a list of QStrings.
-
-    In addition to the locale and collation strategy, several optional flags can
-    be set that influence the result of the collation.
