The "custom-code" script is a simple noweb filter that allows for some
very simple typesetting of code chunks.  It simply inserts a 

	\bgroup\nwcustomcode ... \egroup

wrapper around everything in code chunks and quoted code.  The user
simply defines the \nwcustomcode macro to typeset the code
appropriately.  This is primarily useful for programming languages like
Neliac (and, perhaps, APL), which use specialized character sets (and
don't look quite right when rendered in ``standard'' ASCII characters.

The "example.nw" file demonstrates "custom-code" in action.  Simply

	noweave -t4 -delay -index example.nw -filter custom-code >example.tex

and run the result through LaTeX for a sample of the same code both
with and without the custom typesetting.
