BurrTools is a library to solve burr-type puzzles. Bundled with the library comes a graphical program that lets you edit the puzzles and view the found solutions. The real documentation is inside the executable-file as on-line help. And also available as a pdf for off-line reading or printouts. I've also been able to bundle a few puzzles with the program to demonstrate its features. Thanks to the designers. You can find these puzzles in the examples subdirectory. The library that contains all the mathematical and algorithmical stuff is documented using doxygen. You can generate that documentation using the doxygen.cfg file that is in the source-code of the program. I tried to include algorithmic as well as organisatorical comments into the doxygen documentation. Have fun. Andreas Röver
