+# This script is fed to pbuilder to build Debian packages. The base tarball
+# should be created with a command similar to the following:
+#
+#   sudo pbuilder create --basetgz pbuilder-arsse.tgz --mirror http://ftp.ca.debian.org/debian/ --extrapackages debhelper --extrapackages devscripts
+#
+# Thereafter pbuilder can be used to build packages with this command:
+#
+#   sudo pbuilder execute --basetgz pbuilder-arsse.tgz --bindmounts `basedir "/path/to/release/tarball"` -- pbuilder.sh "/path/to/release/tarball"
+#
+# This somewhat roundabout procedure is used because the pbuilder debuild
+# command does not seem to work in Arch Linux, nor does pdebuild. Doing
+# as much as possible within the chroot itself works around these problems.
