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

+%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 [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]

+%D And these. We typeset itemizations ragged right.

+\setupitemgroup

+\setupitemgroup

+  [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.

+%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.
