+  \class ColorOutput
+  \since 4.4
+  \nonreentrant
+  \brief Outputs colored messages to \c stderr.
+  \internal
+
+  ColorOutput is a convenience class for outputting messages to \c
+  stderr using color escape codes, as mandated in ECMA-48. ColorOutput
+  will only color output when it is detected to be suitable. For
+  instance, if \c stderr is detected to be attached to a file instead
+  of a TTY, no coloring will be done.
+
+  ColorOutput does its best attempt. but it is generally undefined
+  what coloring or effect the various coloring flags has. It depends
+  strongly on what terminal software that is being used.
+
+  When using `echo -e 'my escape sequence'`, \c{\033} works as an
+  initiator but not when printing from a C++ program, despite having
+  escaped the backslash.  That's why we below use characters with
+  value 0x1B.
+
+  It can be convenient to subclass ColorOutput with a private scope,
+  such that the functions are directly available in the class using
+  it.
+
+  \section1 Usage
+
+  To output messages, call write() or writeUncolored(). write() takes
+  as second argument an integer, which ColorOutput uses as a lookup
+  key to find the color it should color the text in. The mapping from
+  keys to colors is done using insertMapping(). Typically this is used
+  by having enums for the various kinds of messages, which
+  subsequently are registered.
+
+  \code
+  enum MyMessage
+  {
+    Error,
+    Important
+  };
+
+  ColorOutput output;
+  output.insertMapping(Error, ColorOutput::RedForeground);
+  output.insertMapping(Import, ColorOutput::BlueForeground);
+
+  output.write("This is important", Important);
+  output.write("Jack, I'm only the selected official!", Error);
