   3 ## applypatch takes four file arguments, and uses those to
   4 ## apply the unpacked patch (surprise surprise) that they
   5 ## represent to the current tree.
   6 ##
   7 ## The arguments are:
   8 ##      $1 - file with commit message
   9 ##      $2 - file with the actual patch
  10 ##      $3 - "info" file with Author, email and subject
  11 ##      $4 - optional file containing signoff to add
  12 ##
  13 . git-sh-setup-script || die "Not a git archive."

  17 ## If this file exists, we ask before applying
  18 ##

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