When use md5sum to identify files, the long hex is hard to read or communicate with human. Since MD5 is an 128-bit hash code, and linux works have more then 64K lines (words), md5sum can been mapped to 8 words. So I start to write this tiny program .\c_src empty now .\Doc empty now README.TXT .\sh_src linux sh script to map md5sum to cleanwords. .\Tools linux sh script to get cleanwords (All asc chars "a-z A-Z")
