# sbosrcarch client example script. tested with bash, ash, ksh.
# known not to work with zsh.

# if you want a fancier client, that's smart enough to try several
# archive sites, plus well-known source archives like gentoo and
# freebsd, plus archive.org's wayback machine, have a look at:

# http://urchlay.naptime.net/repos/sbostuff/plain/sbofindsrc

# path to the root of your archive (contains the by-name and
# by-md5 directories).
ARCHIVE=http://slackware.org.uk/sbosrcarch/
