+%D \macros
+%D   {compound}
+%D
+%D We will overload the already active \type {|} so we have
+%D to save its meaning in order to be able to use this handy
+%D macro.
+%D
+%D \starttyping
+%D so test\compound{}test can be used instead of test||test
+%D \stoptyping
+
+\bgroup \catcode\barasciicode\activecatcode \gdef\compound#1{|#1|} \egroup

+%D Here we hook some code into the clean up mechanism needed
+%D for verbatim data.

+%D The following code will me mkiv'd when needed. It's rather easy to
+%D extend the kerner with glue.

+%D \macros
+%D   {stretched}
+%D
+%D Stretching characters in a word is a sort of typographical
+%D murder. Nevertheless we support this manipulation for use in
+%D for instance titles.
+%D
+%D \starttyping
+%D \hbox to 5cm{\stretched{murder}}

+%D \stretched{Unknown Box}
+%D \hbox to .5\hsize{\stretched{A Horizontal Box}}
+%D \vbox to 2cm{\stretched{A Vertical Box}}
+%D \hbox to 3cm{\stretched{sp{\'e}c{\`\i}{\"a}l}}
+%D \stopbuffer
+%D
+%D \getbuffer
+%D
+%D The first line of this macros takes care of boxing. Normally
+%D one will use an \type{\hbox} specification. The last line
+%D shows how special characters should be passed.
+%D
+%D \typebuffer

+%D \macros
+%D   {stretchednormalcase, stretcheduppercase, stretchedlowercase}
+%D
+%D A convenient alternative is:
+%D
+%D \starttyping
+%D \stretcheduppercase{Is this what you like?}
+%D \stoptyping
+%D
+%D \typebuffer
+%D
+%D this one uses fixed skips and kerns.

+%D \startexample
+%D \getbuffer
+%D \stopexample
