-%D Moved from math-new.tex (not that new anyway:
-
-%D \macros
-%D {genfrac}
-%D
-%D [TH] The definition of \type {\genfrac} \& co. is not
-%D trivial, because it allows some flexibility. This is
-%D supposed to be a user||level command, but will fail quite
-%D desparately if called outside math mode (\CONTEXT\ redefines
-%D \type {\over})
-%D
-%D [HH] We clean up this macro a bit and (try) to make it
-%D understandable. The expansion is needed for generating
-%D the second argument to \type {\dogenfrac}, which is to
-%D be a control sequence like \type {\over}.

-%D For thee moment here, but it might move:
-
-%D \macros
-%D {qedsymbol}
-%D
-%D [HH] The general Quod Erat Domonstrandum symbol is defined
-%D in such a way that we can configure it. Because this symbol
-%D is also used in text mode, we make it a normal text symbol
-%D with special behavior.
-
-\unexpanded\def\qedsymbol#1%
- {\ifhmode
- \unskip~\hfill#1\par
- \else\ifmmode
- \eqno#1\relax % Do we really need the \eqno here?
- \else
- \leavevmode\hbox{}\hfill#1\par
- \fi\fi}
-
-\definesymbol [qed] [\qedsymbol{\mathematics{\square}}]
-
-%D \macros
-%D {QED}
-%D
-%D [HH] For compatbility reasons we also provide the \type
-%D {\QED} command. In case this command is overloaded, we still
-%D have the symbol available. \symbol[qed]
-
-\unexpanded\def\QED{\symbol[qed]}
-
-%D \macros
-%D {mathhexbox}
-%D
-%D [TH] \type {\mathhexbox} is also user||level (already
-%D defined in Plain \TEX). It allows to get a math character
-%D inserted as if it was a text character.
-
-\unexpanded\def\mathhexbox#1#2#3%
- {\mathtext{$\mathsurround\zeropoint\mathchar"#1#2#3$}}
-
-%D \macros
-%D {boxed}
-%D
-%D [HH] Another macro that users expect (slightly adapted):
-
-\unexpanded\def\boxed
- {\ifmmode\expandafter\mframed\else\expandafter\framed\fi}
