math­b­bol – Use the bbold fonts in math­e­mat­ics

Macros for us­ing the bbold fonts (in­clud­ing some re­lated sym­bols taken from the stmaryrd fonts). The pack­age it­self needs two .fd files (to be found in the down­loaded di­rec­tory) to op­er­ate.
The file is part of Jörg Knap­pen’s col­lec­tion.
