+# Little common functions

+# push a mirror attached to us.
+# Arguments:
+# $1 - Name for the mirror, also basename for the logfile
+# $2 - Hostname to push to
+# $3 - Username there
+# $4 - Protocol version, either 1 or 2.
+# $5 - the ssh private key file to use for this push
+# $6 - any other option ssh accepts, passed blindly, be careful
+#
+# This function assumes that the variable LOG is set to a directory where
+# logfiles can be written to.
+# Pushes will be done in background.
