How to use buildinstall for building a custom distro

["Lee, Myoung Ho" <backdrum@xxxxxxxxxxx>]

I built install directory structure under "i386" directory.

When I run 'genhdlist' script, I finished successfully. 
but buildinstall script just print out the usage();
    [root@rh9 i386]# buildinstall \
    > --pkgorder /work/i386/pkgorder.txt \
    > --comp dist-8.0 \
    > --version 8.0 \
    > --release "my distro" \
    >  /work/i386
    Usage: buildinstall [--comp <component>] [--pkgorder <file>] [--version <version
    >] [--product <product>] [--release <comment>] <root>

Should I make pkgorder.txt before run buildinstall or do anything else??
