I look forward to the upcoming documentation for Boost Build version 2
subsequent to the 1.33 release.

I can see the "-sBUILD" there but it tells me nothing about any of the options I
can use with it, other than to say there are some. This to me is almost
laughable, that the documentation would make a point of saying 'Of the
additional options perhaps the most imporant is "-sBUILD=<features/variants>"
which lets you override what is built by default' but then there is no
documentation anywhere telling me what the options are and what they mean, other
than to give the default string, again without explaining what it means. I say
this in all good spirits that "you just have to be kidding" if anybody considers
this adequate documentation. It is rather like something out of Ionesco instead.

Considering that you pointed out to me how I could control my build of the Boost
libraries by defining BOOST_ALL_DYN_LINK using BUILD, I find it very odd that
you say that "BUILD is not really intended for end users". Is it not an end-user
possibility to control Boost build by specifying the correct command line options ?

Thanks for the link.
