       This module is for testing XML::Twig handlers.

       All functions are exported.

       get_twig ( INPUT [, ARGS ] )
           Return  a parsed twig of INPUT, or undef on parse failure.  Optionally, ARGS may be supplied as a set
           of hash-like parameters to be passed into the twig constructor.

       test_twig_handler ( HANDLER, INPUT, EXPECTED, TESTNAME [, COND ] )
           Parse INPUT, using HANDLER as a twig_handler (i.e: it gets called  after  the  parse  tree  has  been
           built).   Tests  that  the  result  is the same as EXPECTED (which can be either a string of XML or a
           quoted regex).  HANDLER must be a code ref.

           Optionally, COND can be supplied.  Instead of the handler being  called  with  the  root  element  of
           INPUT, COND will be used with first_child() to select an alternative element.

           Returns true / false depending upon test success.

       test_twig_handlers ( ARGS, INPUT, EXPECTED, TESTNAME )
           This  is  similar  to test_twig_handler(), but with more flexibility.  The first argument, ARGS, is a
           hash reference which can be used to specify any of the ordinary  parameters  to  twig's  constructor.
           This lets you test things like start_tag_handlers, as well as multiple twig_handlers together.
