Due to high maintenance cost of scripts related to the Arch Build System, we have decided to deprecate the `abs` tool and thus rsync as a way of obtaining PKGBUILDs.
The `asp` tool, available in [extra], provides similar functionality to `abs`. `asp export pkgname` can be used as direct alternative; more information about its usage can be found in [the documentation][asp]. Additionally Subversion sparse checkouts, as described [here][svn], can be used to achieve a similar effect. For fetching all PKGBUILDs, the best way is cloning the [svntogit][git] mirrors.
While the `extra/abs` package has been already dropped, the rsync endpoint (rsync://rsync.archlinux.org/abs) will be disabled by the end of the month.
