Subject: [boost] Variadic Data Library in sandbox

I have put in the sandbox the Variadic Macro Data library, or VMD. This
library supplies variadic macro functionality and integrates variadic
macros with the Boost PP library without changing the latter in any way.
The library in the sandbox is in the variadic_macro_data folder. The
library is a header-only library of macros. There is documentation and
tests and the appropriate jamfiles for both. To build the documentation
you need doxygen but I have also provided documentation in an html

The main use of the library is to be able to pass variadic data to
macros, and in particular to extract variadic data elements or convert
variadic data to Boost PP data types for use by Boost PP. The library
also enhances the Functionality of Boost PP tuple data.

Installation is simply to take the boost and lib subfolders of the
library and copy them to a Boost installation, preferable the trunk
where support for variadic macros has been added in Boost config in the
form of a BOOST_NO_VARIADIC_MACROS which is defined for
compilers/versions which do NOT support variadic macros. To use the
macros in the library, just "#include
<boost/variadic_macro_data/VariadicMacroData.hpp>". Compilers which
support variadic macros are gcc 3.0 and above and VC8 ( VS2005 ) and
above among a few others.

There is a discussion in the doc of why you might choose to use variadic
macros rather than a Boost PP data type in a macro tailored for end-users.

Comments, suggestions, and bug reports are welcome.
