How do I put accessory scripts in a Makefile ?

[Jon Drews]

Port: editors/ted
Version: 2.17
on:   5.3-STABLE FreeBSD 5.3-STABLE #0: Mon Jan 31

I have 

do-install:
        ${INSTALL_PROGRAM} ${WRKSRC}/Ted/Ted ${PREFIX}/bin
        ${INSTALL_SCRIPT} ${WRKSRC}/tedPackage/Ted ${PREFIX}/bin
        @${MKDIR} ${AFMDIR}
        ${INSTALL_DATA} ${WRKSRC}/tedPackage/afm/* ${AFMDIR}
        @${MKDIR} ${INDDIR}
        ${INSTALL_DATA} ${WRKSRC}/tedPackage/ind/US_English.ind ${INDDIR}

That is I want to install rtf2pdf.sh and rtf2ps.sh from
/usr/ports/editors/ted/work/Ted-2.17/tedPackage/Ted into
/usr/X11R6/bin/. Is the line ${INSTALL_SCRIPT}
${WRKSRC}/tedPackage/Ted ${PREFIX}/bin  the correct way to do it?

                                                                 Kind regards,
                                                                 Jonathan
