# The Boost web site provides free peer-reviewed portable
  # C++ source libraries. The emphasis is on libraries which
  # work well with the C++ Standard Library. The libraries are
  # intended to be widely useful, and are in regular use by
  # thousands of programmers across a broad spectrum of applications.

  # Oh yippee, a new build system, it's sooo cooool I could eat my own
  # foot.  inlining=on lets the compiler choose, I think.  At least this
  # stuff is documented...
  # NOTE: if you leave <debug-symbols>on then in a debug build the build sys
  # objcopy will be invoked, and that won't work.  Building debug apparently
  # requires hacking gcc-tools.jam
  #
  # Sometimes I wake up screaming.  Famous figures are gathered in the nightmare,
  # Steve Bourne, Larry Wall, the whole of the ANSI C committee.  They're just
  # standing there, waiting, but the truely terrifying thing is what they carry
  # in their hands.  At first sight each seems to bear the same thing, but it is
  # not so for the forms in their grasp are ever so slightly different one from
  # the other.  Each is twisted in some grotesque way from the other to make each
  # an unspeakable perversion impossible to perceive without the onset of madness.
  # True insanity awaits anyone who perceives all of these horrors together.
  #
  # Quotation marks, there might be an easier way to do this, but I can't find
  # it.  The problem is that the user.hpp configuration file must receive a
  # pre-processor macro defined as the appropriate string - complete with "'s
  # around it.  (<> is a possibility here but the danger to that is that the
  # failure case interprets the < and > as shell redirections, creating
  # random files in the source tree.)
