+ * Disable by defining the preprocessor variable NDEBUG prior to inclusion.
+ *
+ * The following macros sould be defined as string literals
+ *
+ * 	name			value
+ *
+ * 	__MODULE__		Name of module. eg. "libfoo"
+ *
+ * 	__FILE__		Name of file. eg. "foo.c"

+ *	__FUNCTION__		Name of enclosing function. eg. "bar"
+ *
+ * 	(inteter literal)
+ * 	__LINE__		Number of enclosing line.
+ *
+ *
+ * __FILE__, and __LINE__ are automatically defined by standard CPP
+ * implementations. __FUNCTION__ is more or less unique to GNU, and isn't
+ * strictly a preprocessor macro, but rather a reserved word in the compiler.
+ * There is a sed script available with this toolset that is able to fake
+ * __FUNCTION__ (among other things) with an extra preprocesessing step.
+ *
+ * __MODULE__ is nonstandard and should be defined the enclosing program(s).
+ * Autoconf defines PACKAGE as the module name, and these routines will use its
+ * value instead if __MODULE__ is undefined.
+ *
+ * The following routines are provided (as macros) and take the same arguments
+ * as printf():
+ *
+ * MESSAGE( const char *format, ... )
+ * WARNING( const char *format, ... )
+ * FATAL( const char *format, ... )
+ *
+ * Calling MESSAGE or WARNING prints the message to stderr along with module,
+ * file and line information, as well as appropriate emphasis. Calling
+ * FATAL will do the same, and then call abort() to end the program. It is
+ * unwise to supply any of these marcros with arguments that produce side
+ * effects. As, doing so will most likely result in Heisenbugs; program
+ * behavior that changes when debugging is disabled.
