swap endianess of a cram filesystem (cramfs)
cramfs is a highly compressed and size optimized linux filesystem which is mainly used for embedded applications. the problem with cramfs is that it is endianess sensitive, meaning you can't mount a cramfs for a big endian target on a little endian machine and vice versa. this is often especially a problem in the development phase. . cramfsswap solves that problem by allowing you to swap to endianess of a cramfs filesystem.
