+      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.
