VeriTAR [Veri(fy)TAR] is a command-line utility that verifies the MD5 sums of files within a tar archive. Due to the limitations of the tar ("ustar") format, the MD5 sums are retrieved from a separate file and are checked against the MD5 sums of the files within the tar archive. The process takes place without actually exctracting the files. It works even with corrupted tar archives. The program carries on to the next file within the archive, skipping the damaged parts. At the moment, this relies on internal functions of Python's tarfile module.
Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
