+% The grabbed math is at first passed to the processor. The processor is not called
+% in a measuring phase (from the amsmath \cs{ifmeasuring@}) and if the \cs{m at th} 
+% token is detected. 
+% It is not quite clear what purpose the processor has. As it is a public interface
+% it can't be used for internal code. And typesetting happens later and the processor
+% can't really change this. Currently it is mostly used for debugging and messages.
+% If the \cs{m at th} is found the \cs{l_@@_fakemath_bool} is set, so if the code
+% is changed this must be preserved.
