/* c.dot - Don Yang (uguu.org)

   C/C++ comments:
      strings = text quoted by ' or ", can contain escaped
                characters preceded by \
      comments = text outside strings, enclosed by / * * /
      single line comments = text outside strings, from // until end
                             of line.

   Other languages where this applies: Java, JavsScript, C#, dot,
   yacc.  Almost compatible with D, except the /+ +/ comments are not
   supported.
                                                                           */
