psync is a distribution mirroring utility with consistency in mind.
psync is a mirroring utility. its main goal is to be able to update a distribution mirror but keep it as consistent as possible. one of the main problems updating a mirror is that if the mirroring process is stopped for any reason, the mirror stays inconsistent: either some of the packages in the old databases were removed or not all the new packages were downloaded. psync aims to fix this. it also aims to support as many distributions as possible.
