Re: [jamboost] Pitfall -- environment variables

Hi Richard,

Your ideas are excellent. However, we're trying not to do too much more
work on Boost.Build v1 and we /really/ hope that v2 will rely much less
on environment variables. Of course, it seems likely to me that we'll
still use some environment variables to do default configuration (e.g.
detecting the OS). We'll be sure to document a method to find out what
configuration the build system thinks it's got, and a method for
explicitly telling it what configuration it should have.

How doesn that sound?
