13 [Boost 1.44: Proto gets sub-domains and per-domain control of _as_expr_
14 and _as_child_ to meet the needs of Phoenix3.]
18 [Proto v4 is merged to Boost trunk with more powerful transform protocol.]
22 [Proto is accepted into Boost.]
26 [Proto's Boost review begins.]
30 [Boost.Proto v3 brings separation of grammars and transforms and a
31 "round" lambda syntax for defining transforms in-place.]
35 [Boost.Xpressive is ported from Proto compilers to Proto transforms.
36 Support for old Proto compilers is dropped.]
40 [Preliminary submission of Proto to Boost.]
44 [The idea for transforms that decorate grammar rules is born in a private
45 email discussion with Joel de Guzman and Hartmut Kaiser. The first
46 transforms are committed to CVS 5 days later on December 16.]
50 [The idea for `proto::matches<>` and the whole grammar facility is
51 hatched during a discussion with Hartmut Kaiser on the spirit-devel list.
52 The first version of `proto::matches<>` is checked into CVS 3 days later.
53 Message is [@http://osdir.com/ml/parsers.spirit.devel/2006-11/msg00003.html here].]
57 [Proto is reborn, this time with a uniform expression types that are POD.
58 Announcement is [@http://lists.boost.org/Archives/boost/2006/10/112453.php here].]
62 [Proto is born as a major refactorization of Boost.Xpressive's
63 meta-programming. Proto offers expression types, operator overloads and
64 "compilers", an early formulation of what later became transforms.
