#! @BASH@# This is a wrapper to GNU patch that recognizes the most common# options and mimics GNU patch's behavior and output, and creates the# quilt metadata as if quilt push was used to apply the patches.  When# options are used that this wrapper does not recognize, GNU patch is# used directly, and no quilt metadata will get created.PATCH=@PATCH@original_options=("$@")# GNU patch recognizes these environment variablesif [ -n "$SIMPLE_BACKUP_SUFFIX" ]then    set -- --suffix "$SIMPLE_BACKUP_SUFFIX" "$@"fiif [ -n "$PATCH_VERSION_CONTROL" ]then    set -- --version-control "$PATCH_VERSION_CONTROL" "$@"elif [ -n "$VERSION_CONTROL" ]then    set -- --version-control "$VERSION_CONTROL" "$@"fiif [ -n "$POSIXLY_CORRECT" ]then    set -- --posix "$@"fibackup_files() {    declare dir=${QUILT_PC:-.pc}/$patch    if [ "$backup_mode" = --backup-if-mismatch ]    then	awk '	/^patching file / \	    { file=$0	      sub(/^patching file /, "", file)	    }	/^Hunk #[0-9]* / \	    { if (!(file in backup)) {	        backup[file] = 1	        #print "ln -f "dir"/"file" "prefix file suffix > "/dev/stderr"	        system("ln -f "dir"/"file" "prefix file suffix)	      }	    }	    { if (!silent)	        print	    }	' dir="${dir//\\/\\\\}" \	  prefix="${opt_prefix//\\/\\\\}" \	  suffix="${opt_suffix//\\/\\\\}" \	  silent="${opt_silent:+1}"    elif [ -n "$opt_silent" ]; then	cat > /dev/null    fi    if [ "$backup_mode" = --backup -a -d "$dir" ]    then	for file in $(find "$dir" -type f -a ! -path "$path/.timestamp")	do	    dest=$opt_prefix${file#$dir/}$opt_suffix	    mkdir -p $(dirname "$dest")	    ln -f $file $dest	done    fi}find_pipe_patch() {    declare patch=$1    patch=${patch//\[/\\[}    patch=${patch//\]/\\]}    set -- $(stat -c $'%a %N\n' /proc/*/fd/* 2>/dev/null \	     | sed -nre "s,^300 \`(/proc/.*/fd)/.*' -> \`$patch'$,\\1,p")    set -- $(stat -c $'%a %N\n' $1/* 2>/dev/null \	     | sed -nre "s,^500 \`.*' -> \`(.*)',\\1,p")    [ $# -eq 1 ] || set -- "$patch"    echo "$1"}options=`getopt -q -o bsB:z:i:p:d: \		   --long quiet,silent,backup,backup-if-mismatch \		   --long no-backup-if-mismatch,prefix: \		   --long suffix:,posix,input:,strip:,directory: -- "$@"`if [ $? -ne 0 ]then    cannot_handle=1else	case "${LC_ALL:-${LC_MESSAGES:-${LANG}}}" in	''|C|POSIX|en*)		;;	*)	cannot_handle=1		;;	esacfiif [ -z "$cannot_handle" ]; then    eval set -- "$options"    backup_mode=--backup-if-mismatch    opt_prefix=    opt_suffix=    opt_silent=    opt_input=    opt_strip=    opt_directory=$PWD    while :    do	case "$1" in	-b|--backup)	    backup_mode=--backup	    ;;	--backup-if-mismatch)	    backup_mode=--backup-if-mismatch	    ;;	-d|--directory)	    cd "$2" || exit 1	    shift	    ;;	-i|--input)	    opt_input=$2	    new_options[${#new_options[@]}]=$1	    new_options[${#new_options[@]}]=$2	    shift	    ;;	--no-backup-if-mismatch)	    backup_mode=--no-backup-if-mismatch	    ;;	-B|--prefix)	    opt_prefix=$2	    new_options[${#new_options[@]}]=$1	    new_options[${#new_options[@]}]=$2	    shift	    ;;	-s|--silent|--quiet)	    opt_silent=--silent	    ;;	-p|--strip)	    opt_strip=-p$2	    new_options[${#new_options[@]}]=-p$2	    shift	    ;;	-z|--suffix)	    opt_suffix=$2	    new_options[${#new_options[@]}]=$1	    new_options[${#new_options[@]}]=$2	    shift	    ;;	--posix)	    backup_mode=--no-backup-if-mismatch	    new_options[${#new_options[@]}]=$1	    ;;	--)	    shift	    break	    ;;	*)	    new_options[${#new_options[@]}]=$1	    ;;	esac	shift    done    [ -n "$opt_prefix$opt_suffix" ] || opt_suffix=.orig    if [ -z "$opt_strip" -o $# -ne 0 ]    then	cannot_handle=1    fifiif [ -z "$cannot_handle" ]then    if [ -n "$opt_input" ]    then	patch=$opt_input    elif [ -e /proc/self/fd/0 ]    then	patch=$(readlink /proc/self/fd/0)	case "$patch" in	pipe:*)		patch=$(find_pipe_patch "$patch")		;;	esac    fi    patch=${patch#$PWD/}    if [ ! -e "$patch" ]    then	cannot_handle=1    fifiif [ -n "$cannot_handle" ]then    $PATCH "${original_options[@]}"    exitfiquilt_patches=${QUILT_PATCHES:-patches}dir=$(dirname "$quilt_patches/$patch")mkdir -p "$dir"if [ -e "$patch" ]then    if [ "${patch:0:1}" = / ]    then	ln -s "$patch" "$quilt_patches$patch"	patch=${patch#/}    else	while !
