11%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
12%C details.

14%D In boring module we define a lot of obscure but useful system constants.
15%D By doing so we save lots of memory while at the same time we prevent
16%D ourself making typing errors.

22%D This file is mostly the same as the \MKII\ variant but we keep extending
23%D \MKIV, so it was bout time to have a dedicated variant.
24%D
25%D The constants are grouped in such a way that there is a minimal change of
26%D conflicts.
