The formal review for the Spirit Parser Framework begins today, and runs
until the end of Sunday 20th October.

Discussion should take place on the main boost developer list
(boost_at_[hidden]), please state in your review whether you think the
framework should be accepted into boost or not.

The framework can be downloaded from:


Spirit is an object oriented recursive descent parser generator framework
implemented using template meta-programming techniques. Expression templates
allow us to approximate the syntax of Extended Backus Normal Form (EBNF)
completely in C++. Parser objects are composed through operator overloading
and the result is a backtracking LL(inf) parser that is capable of parsing
rather ambiguous grammars.

The Spirit framework enables a target grammar to be written exclusively in
C++. Inline EBNF grammar specifications can mix freely with other C++ code
and, thanks to the generative power of C++ templates, are immediately
executable. In retrospect, conventional compiler-compilers or
parser-generators have to perform an additional translation step from the
source EBNF code to C or C++ code.
