34%D \TUGBOAT\ uses slightly different interline space than the default. So we change
35%D the interline space.

49%D \TUGBOAT\ uses Computer Modern fonts, and \CONTEXT\ uses Latin Modern by default.
50%D So, we just specify the font size.

53  [10pt]
54
55%D We break after these chars in urls, not before.

61%D The original layout used in the \LATEX\ style for \TUGBOAT\ is a bit ambiguous.
62%D It uses low|-|level \TEX\ syntax, rather than changing the layout in a human
63%D understandable way (for example, by using the \mono{geometry} package. I have
64%D tried to translate it to \CONTEXT\ as far as I understand.

93%D In \TUGBOAT\ different articles are glued together to form the final journal, so
94%D we do not want each article to occupy even number of pages.

97
98%D We use automatic indentation control, that is: no indentation after titles and
99%D skips.

129
130%D We follow the \TUGBOAT\ style for sections. I do not know if \type {align=right}
131%D also disables hyphenation. Lets wait and see on this. Rest all is straight
132%D forward. It took me a while to realize that in \LATEX\ \type {\@startsection} the
133%D absolute value of before skip (fourth argument) is important and not the sign.

142
143%D We define a logical skip. This is equal to the \tex{topsep} in the normal style,
144%D and most environments should have this skip.
