[section Acknowledgments]

I am indebted to [@http://boost.org/people/joel_de_guzman.htm Joel de Guzman]
and [@http://boost.org/people/hartmut_kaiser.htm Hartmut Kaiser] for their
expert advice during the early states of xpressive's development. Much of
static xpressive's syntax is owes a large debt to _spirit_, including the
syntax for xpressive's semantic actions. I am thankful for
[@http://boost.org/people/john_maddock.htm John Maddock]'s excellent work on
his proposal to add regular expressions to the standard library, and for
various ideas borrowed liberally from his regex implementation. I'd also like
to thank [@http://moderncppdesign.com/ Andrei Alexandrescu] for his input
regarding the behavior of nested regex objects, and
[@http://boost.org/people/dave_abrahams.htm Dave Abrahams] for his suggestions
regarding the regex domain-specific embedded language. Noel Belcourt helped
porting xpressive to the Metrowerks CodeWarrior compiler. Markus
Sch'''ö'''pflin helped to track down a bug on HP Tru64, and Steven
Watanabe suggested the fix.

Special thanks are due to David Jenkins who contributed both ideas, code and
documentation for xpressive's semantic actions, symbol tables and attributes.
Xpressive's ternary search trie implementation is David's, as is the number
parser example in [^libs/xpressive/example/numbers.cpp] and the documentation
for symbol tables and attributes.

Thanks to John Fletcher for helping track down a runtime assertion when using
xpressive with Howard Hinnant's most excellent libc++.

Finally, I would like to thank [@http://boost.org/people/thomas_witt.html Thomas Witt]
for acting as xpressive's review manager.
