   Python comments:
      strings = text quoted by ', ", ''', or """, can contain
                escaped characters preceded by \
      comments = text outside strings, from # until end of line.

   Note that the above definition is an over simplication.  In
   particular, documentation strings are not recognized.

   The # syntax is also somewhat compatible with other scripting
   languages, including Perl, Ruby, sh/bash/csh, awk, etc.  Python is
   the simplest of them all (doesn't have POD and other more complex
   bits).
                                                                           */
