Hapy 0.0.5 is available

Hi,

	Hapy library version 0.0.5 has been released.
The fifth release contains major performance optimizations
and minor bug fixes/improvements.

The change log is below.

Enjoy,

Alex.

0.0.5 2004/03/04:
    - enable debugging if the code writer did not explicitly
      prohibit it by calling Rule::Debug(false), and the code
      runner set the HAPY_DEBUG environmental variable to
      "USER"; this allows debugging of previously compiled
      programs without modifying their code
    - parsing speed and greed optimizations
    - added dedicated user-level interfaces for controlling
      debugging and optimization: Hapy::Debug() and
      Hapy::Optimize()
    - when debugging, report rejection due to left recursion
      or empty sequence repetition
    - use AX_PREFIX_CONFIG_H autoconf macro to prefix
      config.h #defines with a HAPY_ prefix, to avoid
      conflicts with other libraries using autoconf
    - do not #include config.h if HAVE_CONFIG_H or
      HAPY_HAVE_CONFIG_H is not defined; always include Top.h
      though
    - changed left recursion detection algorithm to take care
      of cases where the parsing rule is repeated without
      visible progress but the second appearance may lead
      (once the duplicate path is rejected) to a different
      path, making progress; added an indirectRecursion test
      case to make sure we always handle this kind of
      recursion correctly
    - added UselessRecursion test case, mainly to test
      handling of A = A kind of rules; this test case exposed
      the problem with the negative operator (A - B): when
      placed at the top of the grammar, the exceptional rule
      (B) may not match end of input while the user may
      expect it to; explicit end_r rule would be required to
      parse (A - B) correctly at the top of the grammar
    - Pree::rid() now returns RuleId, not int
