* is loaded and included into the properties. Note that the keys in
* this $section will override any keys of the same
* name in the sections that have been included via ":".
*
* If the $section is null, then all sections in the ini file are loaded.

* [all]
* db.connection = database
* hostname = live
*
* [staging : all]
* hostname = staging
*
