%D
%D \subsection{Typesetting reST-Files}
%D
%D \macros
%D {typesetRSTfile}
%D
%D This command loads and processes an \type{*.rst} file.
%D All necessary setups for the elements to be used (e.g. tables)
%D have to be specified {\em before} this macro is called.
%D As \type{\typesetRSTfile} is intended to process a single file
%D only, it will handle \type{\start|stoptext} automatically.
%D Thus, the user should never supply any of these manually,
%D neither before nor after \type{\typesetRSTfile}.
%D
%D We now handle rogue utf-8 byte order marks on demand, just set
%D the optional parameter \type{stripBOM} to {\em true}.
%D
%D There also is an option \type{expandtab} to convert tabs
%D (ascii 0x09) to indents prior to converting reST input. The
%D expansion width defaults to {\em 4} and can be configured
%D through the parameter \type{shiftwidth} (takes an integer).

%D \subsection{Typesetting Inline Snippets}
%D
%D reST markup can be handy in situations where \CONTEXT\ markup
%D would result in unappropriately verbose source code, e.g. when
%D typesetting tables with simple layout.
%D
%D \macros
%D {RST,startRST}
%D
%D The environment \type{\[start|stop]RST} and the macro
%D \type{\RST} allow access to reST-parser from inside a
%D \CONTEXT\ document when the module is loaded.
%D
%D \showsetup{RST}
%D \showsetup{startRST}

%D \subsection{Including multiple reST files}
%D
%D \macros
%D {defineRSTinclusion,startRSTproject,RSTinclusion}
%D
%D When content is split among multiple files, these macros allow
%D for including them in arbitrary order. Note that setups from
%D previous includes, unless overwritten, will remain defined.
%D \type{\defineRSTinclusion} takes three arguments: the first one
%D will be the identifier that can be used to refer to the actual
%D inclusion, which is specified via the second argument as a
%D filename. The third optional argument receives the usual
%D setups \type{stripBOM}, \type{expandtab} and
%D \type{shiftwidth}.
%D
%D Defined inclusions can be typeset only within an the
%D \type{\startRSTproject} environment using the macro
%D \type{RSTinclusion}. Between those inclusion all kinds of
%D \TEX\ code except for \type{\starttext} and \type{\stoptext}
%D are permitted.
