My company, for example, would be interested in the BGL, but quite unable
to include an LGPL library, since our copy protection mechanism kills the
application if it detects a debugger. This would be a license violation.
(We probably wouldn't need bignum functionality. As long as the BGL can be
used without the bignum libraries, we'd probably be happy.)
