- * MAGPIE_CACHE_ON - Should Magpie cache parsed RSS objects? 
- * For me a built in cache was essential to creating a "PHP-like" 
- * feel to Magpie, see rss_cache.inc for rationale
- *
- *
- * MAGPIE_CACHE_DIR - Where should Magpie cache parsed RSS objects?
- * This should be a location that the webserver can write to.   If this 
- * directory does not already exist Mapie will try to be smart and create 
- * it.  This will often fail for permissions reasons.
- *
- *
- * MAGPIE_CACHE_AGE - How long to store cached RSS objects? In seconds.
- *
- *
- * MAGPIE_CACHE_FRESH_ONLY - If remote fetch fails, throw error
- * instead of returning stale object?
- *
- * MAGPIE_DEBUG - Display debugging notices?
