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

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