This subdirectory contains puzzle implementations which are half-written, fundamentally flawed, or in other ways unready to be shipped as part of the polished Puzzles collection. Those puzzles which have .R files can be built as part of the Puzzles collection by symlinking their source files into the parent directory and re-running mkfiles.pl. Anything without a .R file isn't even finished enough to do that, and you should read the source file itself to find out the status.
