rdup is a utility inspired by rsync and the Plan9 way of doing backups. rdup itself does not backup anything; it only prints a list of the names of files that have changed since the last backup. It also handles files that are removed, allowing for correct incremental backups. Auxilary script that implement a backup strategy are included.

Changes:
The Perl conversion utilities were reimplemented in C as rdup-tr. This utility can be used for all kinds of file transformations (encryption, compression, etc.) and can generate tar, pax, cpio, or rdup ouput. With this release, there are no Perl dependencies left. All shell wrappers and other scripts were dropped from rdup. Numerous little bugs were also fixed.
