    If it's a shell script, you could change it to include
    /lib/lsb/init-functions.

    The function "killproc" *is* in the file /lib/lsb/init-functions, even in Sarge:

    killproc () {
        local pidfile sig status
        set -- `POSIXLY_CORRECT=1 getopt "p:" $*`
        pidfile=

        for i in $*; do
            case $i in
                -p) pidfile=$2; shift 2;;
                --) shift; break;;
            esac
        done

        if [ ! $pidfile ]; then
            pidfile=/var/run/$(basename "$1").pid
        fi

        if [ $2 ]; then
            sig=$(echo $2 | sed -e 's/^-\(.*\)/\1/')
            sig=$(echo $sig | sed -e 's/^SIG\(.*\)/\1/')
            /sbin/start-stop-daemon --stop --pidfile "$pidfile" --signal $sig --quiet
            status="$?"
            [ "$status" = 1 ] && return 3 # program is not running
            return 0
        else
            /sbin/start-stop-daemon --stop --pidfile "$pidfile" --retry 5 --quiet --oknodo
        fi
    }

    Debian unstable uses it, at least:
    $ grep -R killproc /etc/init.d/
    /etc/init.d/autofs: killproc $DAEMON -USR2 >& /dev/null
    /etc/init.d/clamav-freshclam: killproc -p $PIDFILE $DAEMON
    /etc/init.d/clamav-freshclam: killproc -p $PIDFILE $DAEMON 1
    /etc/init.d/clamav-daemon: killproc -p $THEPIDFILE
    /etc/init.d/clamav-daemon: killproc -p $SUPERVISORPIDFILE
    /etc/init.d/clamav-daemon: killproc -p $THEPIDFILE $DAEMON USR2
    /etc/init.d/clamav-daemon: killproc -p $THEPIDFILE $DAEMON 1
