// If this module is loaded after cajita.js is loaded, and in an
// environment (such as produced by turning on Firebug) where
// <tt>console.log</tt> is a function, then it will register 
// a wrapper around <tt>console.log</tt> (or <tt>console.info</tt> 
// and <tt>console.error</tt> if available) using 
// <tt>___.setLogFunc()</tt>, so cajita.js will log its diagnostics
// to the Firebug console.

// If you load triv-logger.js and log-to-console.js into the same
// system, the last one loaded wins.

// This module is written in Javascript, not Caja, and would be
// rejected by the Caja translator.
