+%D The {\em Cyrillic Numbers} module allows the titlo, if requested,
+%D to be drawn in two different ways. If the setup parameter
+%D \type{titlo} has the value {\em mp}, then the variant employing
+%D \METAPOST\ is selected. As there are a couple of different
+%D styles, it will be necessary that the user determine one by
+%D setting the parameter \type{titlomode} to an integer.
+%D Additionally it is possible to manipulate the pen width that
+%D \METAPOST\ uses when executing the titlo code. {\em NB} as the
+%D drawing routines differ, the \type{penwidth} parameter lead to
+%D different results with different modes as well, ymmv.

+%D Conforming to the standard \CONTEXT\ naming scheme as employed

+%D conversions. As there is no definition for uppercase conversion,
+%D the macro \type{\Cyrillicnumerals} exists only for compatibility

+%D {\italic\letterampersand}c. Instead of these predefined ones
+%D the user may consider defining a dedicated conversion routine
