The Math library has a few files not under the Boost Licence: boost/math/common_factor_rt.hpp: *L* Has an SGI style licence left over from previous Boost versions, this is a long standing problem as I've never had a reply from the author about changing this :-( libs/math/doc/sf_and_dist/svgmath.xml: *C*, *L* libs/math/doc/sf_and_dist/xep.xml: *C*, *L* These two files are examples of configuration files required to build the PDF documentation (respectively SVGMath generates SVG graphics from MathML and XEP is the FO processor we've been using - it needs to embed some fonts in order to correctly display the equations). These files are not and can never be under the Boost licence. Originally I was going to embed them in the docs ("if you edit these files edit them like this" etc...), but correctly escaping XML inside quickbook proved rather troublesome :-( Any ideas? We need to formulate some kind of policy for these kinds of ancillary files I guess. Thanks, John.
