%D Maybe we need a more clever system: either command or style mode etc. so
%D that we can avoid the grouped mess in a simple style switch.

%D \macros
%D   {kap,KAP,Kap,Kaps,nokap,userealcaps,usepseudocaps}
%D
%D We already introduced \type{\cap} as way to capitalize
%D words. This command comes in several versions:
%D
%D \startbuffer
%D \cap {let's put on a \cap{cap}}
%D \cap {let's put on a \nocap{cap}}
%D \CAP {let's put on a \\{cap}}
%D \Cap {let's put on a \\{cap}}
%D \Caps{let's put on a cap}
%D \stopbuffer
%D
%D \typebuffer
%D
%D Note the use of \type{\nocap}, \type{\\} and the nested
%D \type{\cap}.
%D
%D \startlines
%D \getbuffer
%D \stoplines
%D
%D These macros show te main reason why we introduced the
%D smaller \type{\tx} and \type{\txx}.
%D
%D \starttyping
%D \cap\romannumerals{1995}
%D \stoptyping
%D
%D This at first sight unusual capitilization is completely
%D legal.
%D
%D \showsetup{smallcapped}
%D \showsetup{notsmallcapped}
%D \showsetup{CAPPED}
%D \showsetup{SmallCapped}
%D \showsetup{SmallCaps}
%D
%D The difference between pseudo and real caps is demonstrated
%D below:
%D
%D \startbuffer
%D \usepseudocaps \cap{Hans Hagen}
%D \userealcaps   \cap{Hans Hagen}
%D \stopbuffer
%D
%D \typebuffer
%D
%D \getbuffer
%D
%D The \type {\bgroup} trickery below is needed because of
%D \type {\groupedcommand}.
