   \class QMacPasteboardMime
-  \brief The QMacPasteboardMime class maps open-standard MIME to Mac flavors.
+  \brief The QMacPasteboardMime class converts between a MIME type and a
+  \l{http://developer.apple.com/macosx/uniformtypeidentifiers.html}{Uniform
+  Type Identifier (UTI)} format.

-  Qt's drag and drop support and clipboard facilities use the MIME
-  standard. On X11, this maps trivially to the Xdnd protocol, but on
-  Mac although some applications use MIME types to describe clipboard
-  formats, others use arbitrary non-standardized naming conventions,
-  or unnamed built-in Mac formats.
-
-  By instantiating subclasses of QMacPasteboardMime that provide conversions
-  between Mac flavors and MIME formats, you can convert proprietary
-  clipboard formats to MIME formats.

-  Qt has predefined support for the following Mac flavors:
+
+  Qt's drag and drop and clipboard facilities use the MIME
+  standard. On X11, this maps trivially to the Xdnd protocol. On
+  Mac, although some applications use MIME to describe clipboard
+  contents, it is more common to use Apple's UTI format.
+
+  QMacPasteboardMime's role is to bridge the gap between MIME and UTI;
+  By subclasses this class, one can extend Qt's drag and drop
+  and clipboard handling to convert to and from unsupported, or proprietary, UTI formats.
+
+  A subclass of QMacPasteboardMime will automatically be registered, and active, upon instantiation.
+
+  Qt has predefined support for the following UTIs:
   \list
-    \i kScrapFlavorTypeUnicode - converted to "text/plain;charset=ISO-10646-UCS-2"
-    \i kScrapFlavorTypeText - converted to "text/plain;charset=system" or "text/plain"
-    \i kScrapFlavorTypePicture - converted to "application/x-qt-image"
-    \i typeFileURL - converted to "text/uri-list"
+    \i public.utf8-plain-text - converts to "text/plain"
+    \i public.utf16-plain-text - converts to "text/plain"
+    \i public.html - converts to "text/html"
+    \i public.url - converts to "text/uri-list"
+    \i public.file-url - converts to "text/uri-list"
+    \i public.tiff - converts to "application/x-qt-image"
+    \i com.apple.traditional-mac-plain-text - converts to "text/plain"
+    \i com.apple.pict - converts to "application/x-qt-image"
   \endlist
 
-  You can check if a MIME type is convertible using canConvert() and
-  can perform conversions with convertToMime() and convertFromMime().
+  When working with MIME data, Qt will interate through all instances of QMacPasteboardMime to
+  find an instance that can convert to, or from, a specific MIME type. It will do this by calling
+  canConvert() on each instance, starting with (and choosing) the last created instance first.
+  The actual conversions will be done by using convertToMime() and convertFromMime().
+
+  \note The API uses the term "flavor" in some cases. This is for backwards
+  compatibility reasons, and should now be understood as UTIs.
