The Ciao mode for Emacs

This is an emacs mode that provides syntax highlighting (font-lock), indentation, source-level debugging and location of errors in source files, access to manuals, maintenance of changelogs, and other editing, compiling, running, and debugging facilities for Ciao programs.

It offers a rich, integrated user interface to the Ciao program development environment components, including the ciaosh interactive top level and the ciaopp preprocessor.
