%D This file is derived t-tugboat by Aditya Mahajan which in turn is derived
%D from older files. Here we use columnsets.

\usemodule[newcolumnsets]

%D We store the information about the article in variables.

%D \TUGBOAT\ uses slightly different interline space than the default. So we change
%D the interline space.

\definebodyfontenvironment    [8pt] [interlinespace=9.5pt, big=9pt,   small=7pt]
\definebodyfontenvironment    [9pt] [interlinespace=11pt,  big=10pt,  small=8pt]
\definebodyfontenvironment   [10pt] [interlinespace=12pt,  big=12pt,  small=9pt]
\definebodyfontenvironment   [12pt] [interlinespace=14pt,  big=14.4pt,small=10pt]
\definebodyfontenvironment [14.4pt] [interlinespace=18pt,  big=14.4pt,small=12pt]

%D We us e italic rather than slanted for emphasis.

\setupbodyfontenvironment
  [default]
  [em=italic]

%D \TUGBOAT\ uses Computer Modern fonts, and \CONTEXT\ uses Latin Modern by default.
%D So, we just specify the font size.

\setupbodyfont
  [10pt]

%D We break after these chars in urls, not before.

%D The original layout used in the \LATEX\ style for \TUGBOAT\ is a bit ambiguous.
%D It uses low|-|level \TEX\ syntax, rather than changing the layout in a human
%D understandable way (for example, by using the \mono{geometry} package. I have
%D tried to translate it to \CONTEXT\ as far as I understand.

%D In \TUGBOAT\ different articles are glued together to form the final journal, so
%D we do not want each article to occupy even number of pages.

\installpagebreakhandler {last} {}

%D We use automatic indentation control, that is: no indentation after titles and
%D skips.

\setupindenting
  [20pt,yes]

%D We do not want indentation after lists.

\setupenumerations [indentnext=no]
\setupdescriptions [indentnext=no]

%D And these. We typeset itemizations ragged right.

\setupitemgroup
  [itemize]
  [indentnext=no,
   align=right]

%D We align them at the paragraph indentation and pack them by default.

\setupitemgroup
  [itemize]
  [each]
  [margin=1pc,
   width=1em,
   distance=0pt]

\setupitemgroup
  [itemize]
  [1]
  [packed]

%D We follow the \TUGBOAT\ style for sections. I do not know if \type {align=right}
%D also disables hyphenation. Lets wait and see on this. Rest all is straight
%D forward. It took me a while to realize that in \LATEX\ \type {\@startsection} the
%D absolute value of before skip (fourth argument) is important and not the sign.

\setuphead
  [section,subsection,subsubsection,
   subject,subsubject,subsubsubject]
  [style=bold,
   align=right,
   before={\blank[8pt]},
   after={\blank[4pt]}]

%D We define a logical skip. This is equal to the \tex{topsep} in the normal style,
%D and most environments should have this skip.

%D \TUGBOAT\ uses a smaller font size for verbatim typesetting.

\setuptyping
  [option=none,
   before={\blank[tugblank]\switchtobodyfont[small]},
   after={\blank[tugblank]}]

%D Not entirely a la \TUGBOAT:

\setupfootnotes
  [bodyfont=8pt,
   location=columns,
   rule=on,
   rulecommand=\MyFootNoteRule]

\setupnotations
  [location=joinedup,
   width=fit,
   headstyle=normal,
   distance=.5em]

%D We define a standard description and enumeration environment.

\definedescription
  [description]
  [location=hanging,
   width=broad,
   before={\blank[tugblank]},
   after={\blank[tugblank]}]

\defineenumeration
  [enumeration]
  [location=hanging,
   width=broad,
   before={\blank[tugblank]},
   after={\blank[tugblank]}]

%D The bib does not handle urls nicely. So we provide a stop gap solution.

\definereferenceformat

  [left={[},
   right={]}]

\defineitemgroup

%D Instead of color, we use weighted gray scales:

%D English it is.

%D We define some logical skips
