+//! \brief The QsciDocument class represents a document to be edited.
+//!
+//! It is an opaque class that can be attached to multiple instances of
+//! QsciScintilla to create different simultaneous views of the same document.
+//! QsciDocument uses implicit sharing so that copying class instances is a
+//! cheap operation.
