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.
Additionally Subversion sparse checkouts, as described here, can
be used to achieve a similar effect. For fetching all PKGBUILDs, the
best way is cloning the svntogit mirrors.
While the extra/abs package has been already dropped, the rsync
endpoint (rsync://rsync.tyrtyr.thefun.eu.org/abs) will be disabled by the end
of the month.
