'''Ctext''' is

   * part of [tklib].

   * a megawidget that is built upon the Tk text widget.  It provides syntax highlighting, and can be used to highlight a variety of languages.  It provides a simple API and more radical changes (other than color) can be made by modifying the tag attributes.  By default matching pairs of characters are flashed on the screen, like the popular Emacs and Lisp editors can do.  

   * licensed like Tcl (BSDish), but copyrighted
