Its similar to CMake and QMake only simpler and more powerful.

The difference is that MPC is simpler (of course others may
disagree that its simpler) and can generate platform specific
build files.

If Boost.Build could generate MSVC files that would be great.

Yes, but it could be simplified.

Step one was to be able to create the main Boost libs and get the
MPC files checked into Boost CVS. If there is interest we can
look into creating MPC files for the tests. We may do that anyway.

I can certainly understand not wanting to maintain more than one
build file. That is the main point of Boost.Build and one of the
key features of MPC. Boost.Build is just missing a key feature
that we at least find very useful, that is generating MSVC (and
other) specific files.

There was some talk of adding (*.sln,*.vcproj) files to Boost
CVS. Hopefully before that was ever done, MPC files would be
added instead.

Thanks for the consideration,
