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 || die "Not a git archive."

15 final=.dotest/final-commit

17 ## If this file exists, we ask before applying
18 ##
19 query_apply=.dotest/.query_apply
20
21 ## We do not munge the first line of the commit message too much
22 ## if this file exists.
