-      QScintilla is a port to Qt of Neil Hodgson's Scintilla C++ editor
-      control.
-
-      As well as features found in standard text editing components,
-      QScintilla includes features especially useful when editing and
-      debugging source code. These include support for syntax styling,
-      error indicators, code completion and call tips. The selection
-      margin can contain markers like those used in debuggers to
-      indicate breakpoints and the current line. Styling choices are
-      more open than with many editors, allowing the use of
-      proportional fonts, bold and italics, multiple foreground and
-      background colours and multiple fonts.
