[Boost-users] Boost Logos

Dear all, I remember that there was a discussion a while ago about logos. Among the proposals was a logo of the type "This code uses Boost". I'd like to acknowledge the great work of the Boost library authors and would thus like to add the logo to the manual of our software. Therefore: I cannot find any "official" logos on the Boost web page that would allow me to do this. What has become of this effort ? Best Regards, Ruediger
