+# has to be able to connect to that host as the builduser via ssh
+# without knowning the password.  This is best achieved with the
+# ssh-agent.  Also, publishstaticweb.py uses rsync to copy files from

+# the directory on build_host where the static web-site should be put.
+# This value is used as the parameter to the build_create command on
+# build_host.
