Updates to the DragonFly source, the ports system, and the dfports system are all performed using cvsup. cvsup compares your local system source or ports files to a remote repository, and downloads any changes. Only the differences in the files are downloaded, saving on bandwidth and time.
cvsup exists as a port (net/cvsup) and traditionally had to be installed separately on FreeBSD. With DragonFlyBSD, the port is installed as part of the base system.
