+//! \brief The QsciLexerCustom class is an abstract class used as a base for
+//! new language lexers.
+//!
+//! The advantage of implementing a new lexer this way (as opposed to adding
+//! the lexer to the underlying Scintilla code) is that it does not require the
+//! QScintilla library to be re-compiled.  It also makes it possible to
+//! integrate external lexers.
+//!
+//! All that is necessary to implement a new lexer is to define appropriate
+//! styles and to re-implement the styleText() method.
