+## applypatch takes four file arguments, and uses those to
+## apply the unpacked patch (surprise surprise) that they
+## represent to the current tree.
+##
+## The arguments are:
+##	$1 - file with commit message
+##	$2 - file with the actual patch
+##	$3 - "info" file with Author, email and subject
+##	$4 - optional file containing signoff to add
+##
+. git-sh-setup-script || die "Not a git archive."

+query_apply=.dotest/.query_apply
+
+## We do not munge the first line of the commit message too much
+## if this file exists.
