; c2html -- print C code to HTML
; By Nils M Holm, 2009-2012
; Placed in the Public Domain
;
; Usage: c2html [-dL] [file ...]
;
; Render C code contained in the given file. When no file
; is given, render stdin. Write output to stdout.
;
; Options:
;
; -d  write a full HTML document (default: PRE block only)
; -L  emit Lout output instead of HTML
;
; The CSS2 style sheet "ccode.css" contains the default style for
; syntax highlighting.
;
; NOTE: This program handles only a subset of C89 correctly.
; Caveat utilitor!
