+## 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 || die "Not a git archive."

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