I was looking for the very simple "crc32" binary to compute checksums for files, and couldn't find it. There is a crc32 perl lib, but no crc32 package. I know that md5 (or even sha-160) hash fingerprints are better, but in many cases (like tar archives on tapes, or ftp files) you have only CRC-32.
See http://freshmeat.net/projects/checkcrc/ This one is looking good, and was co-written by Mark Adler (who also co-wrote zlib) If it was not packaged by anyone (couldn't find any reference, but it might have been packaged with another one), and if everybody is okay, I will ITP it.
