+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+%D Scientific units can be typeset in math mode pretty well,
+%D but occasionally one has to take care of spacing.
+%D Furthermore, entering these units is not that natural as
+%D wanted. Therefore this module presents a more natural way of
+%D doing things, like:
+%D
+%D \starttyping
+%D 1.23 \Cubic \Meter \Per \Second
+%D \stoptyping
+%D
+%D This example shows that we use the order in which we say
+%D things, instead of typeset things. There is a separate
+%D manual for this module.
+
+%D Message number~1 deals with overruling the \type {\Degrees}
+%D macro defined in the core modules. Let's say that this is
+%D an upward compatibility issue.

+%D This runtime loadable module implements a way of defining
+%D units. The core macro is \type {\dimension}, a rather clever
+%D one that is able to cooperate with some other dimension
+%D related macros. As said, this module enables user to enter:
+%D
+%D \startbuffer
+%D some 10 \Square \Meter \Per \Second or more
+%D \stopbuffer
+%D
+%D \getbuffer
+%D
+%D as:
+%D
+%D \typebuffer
+%D
+%D The units itself are implemented as synonyms.
+%D
+%D \starttyping
+%D \definesynonyms [unit] [units] [\unitmeaning]
+%D \setupsynonyms [unit] [textstyle=\dimension]
+%D \stoptyping
+%D
+%D This definition means that we can ask for the meaning of a
+%D unit using \type {\unitmeaning} and get a list of used
+%D units by saying \type {\placelistofunits}
+%D
+%D We have to use the command \type {\unitmeaning} instead
+%D of \type {\meaning}, simply because the latter is a \TEX\
+%D primitive we don't want to loose. We use the label text
+%D mechanism for translations.
+
+%D \macros
+%D {dimension}
+%D
+%D The core of this module is the low level macro \type
+%D {\dimension}. Before presenting this macro, it's best to
+%D look at some applications, because it's supposed to show
+%D some intelligence that can beter be understood from the
+%D context.
+%D
+%D The next useless examples show some of the cases we want
+%D to handle in a proper way.
+%D
+%D \startbuffer
+%D ... 10 \Square \Meter \Per \Volt \
+%D ... 10 \Square \Meter \Volt \
+%D ... 10 \Meter \Volt \
+%D ... 10 \Milli \Square \Meter \Per \Volt \
+%D ... 10 \Square \Milli \Meter \Per \Volt \
+%D ... 10 \Meter \Times \Meter \
+%D ... 10 \Square \Meter \Times \Meter \
+%D ... 10 \Square \Milli \Meter \Times \Meter \
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Becomes:
+%D
+%D \getbuffer
+
+%D \macros
+%D {mathematicstypeface, dimensiontypeface,
+%D dimensionhalfspace, dimensionbackspace}
+%D
+%D There are some low level constants, that can be changed
+%D when needed. Some day I will write a decent setup command.

+%D \macros
+%D {smashdimensionpower}
+%D
+%D Sometimes the baseline distance is not enough to provide
+%D for superscripts, so we smash their height by default.
+
+\newif\ifsmashdimensionpower \smashdimensionpowertrue

+%D The dimension mechanism uses a lot of signals to keep
+%D track if the current state.

+
+%D \macros
+%D {spaceddimensions,textdimensions}
+%D
+%D The actual definition of \type {\dimension} overruled the
+%D one in the core modules. The boolean can be used to
+%D force spacing between units. Vergelijk {\Newton \Meter}
+%D eens met {\spaceddimensionstrue \Newton \Meter}. The
+%D rather ugly test prevents problems with nested dimensions.
+
+\newif\ifspaceddimensions \spaceddimensionsfalse % user switch
+\newif\iftextdimensions \textdimensionsfalse % user switch
+
+%D You can see the consequence of forcing text dimensions
+%D when you compare the following code:
+%D
+%D \starttyping
+%D {\rm test \Square \Meter \Per \Second\ ziezo\Degrees} \par
+%D {\ss test \Square \Meter \Per \Second\ ziezo} \par
+%D {\tt test \Square \Meter \Per \Second\ ziezo}
+%D
+%D \textdimensionstrue
+%D
+%D {\rm test \Square \Meter \Per \Second\ ziezo} \par
+%D {\ss test \Square \Meter \Per \Second\ ziezo} \par
