/* Definition of globally-accessible data items.
*
* This module provides access methods to items of global scope. Most often,
* these globals serve as defaults to initialize local settings. Currently,
* many of them are either constants or global variable references. However,
* this module provides the necessary hooks to change that at any time.
*
* Please note that there currently is no glbl.c file as we do not yet
* have any implementations.
