%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.

%D This module is rather important, because it enables us to define and call for not
%D yet defined fonts in a way completely independant of real font names. First we
%D map some meaningful names onto unknown filenames.

%D This permit us to define (use) fonts that refer to the default style (so, Bold
%D may expand to SansBold or SerifBold, depending on the default style in the
%D typeface). The \LUA\ call is used to set the current alternative in a
%D non|-|interfering way. This make sure that the CurrentFont synonym (in font-sym)
%D is working as expected (e.g.\ in MixedCaps). Yes, this is complicates stuff.

\definefontsynonym[\s!Normal]     [\noexpand\clf_tf\noexpand\v_font_string_d]
\definefontsynonym[\s!Bold]       [\noexpand\clf_bf\noexpand\v_font_string_d\noexpand\s!Bold]

%D Also handy:

\definefontsynonym [Regular]            [Serif]
\definefontsynonym [RegularBold]        [SerifBold]
\definefontsynonym [RegularItalic]      [SerifItalic]

\definefontsynonym [SupportItalic]      [SansItalic]
\definefontsynonym [SupportSlanted]     [SansSlanted]
\definefontsynonym [SupportBoldItalic]  [SansBoldItalic]
\definefontsynonym [SupportBoldSlanted] [SansBoldSlanted]
\definefontsynonym [SupportCaps]        [SansCaps]

%D Well, not that good an idea:

\definefontsynonym [Roman]              [Serif]
\definefontsynonym [RomanBold]          [SerifBold]
\definefontsynonym [RomanItalic]        [SerifItalic]
\definefontsynonym [RomanSlanted]       [SerifSlanted]
\definefontsynonym [RomanBoldItalic]    [SerifBoldItalic]
\definefontsynonym [RomanBoldSlanted]   [SerifBoldSlanted]
\definefontsynonym [RomanCaps]          [SerifCaps]

\definefontsynonym [Type]               [Mono]
\definefontsynonym [TypeBold]           [MonoBold]
\definefontsynonym [TypeItalic]         [MonoItalic]
\definefontsynonym [TypeSlanted]        [MonoSlanted]
\definefontsynonym [TypeBoldItalic]     [MonoBoldItalic]
\definefontsynonym [TypeBoldSlanted]    [MonoBoldSlanted]
\definefontsynonym [TypeCaps]           [MonoCaps]

%D Next we define roman, sans and monospaced font sets.

%D These definitions come into action as soon as names are mapped onto real file
%D names (or names that themselves are mapped).
