-Usage: ${0##*/} [OPTION]... [-- <lustre configure options>]
-
-  -d CVSROOT
-    Specifies the CVS Root to use when pulling files from CVS.  The
-    environment variable \$CVSROOT is used if this option is not
-    present.
-
-  --external-patches=EXTERNAL_PATCHES
-    Directory similar to lustre/lustre/kernel_patches/ that lbuild should
-    look for seres and config files in before looking in the lustre
-    tree.
-
-  --extraversion=EXTRAVERSION
-    Text to use for the rpm release and kernel extraversion.
-
-  --kerneldir=KERNELDIR
-    Directory containing Linux source tarballs referenced by target
-    files.
-
-  --linux=LINUX
-    Directory of Linux kernel sources.  When this option is used, only
-    Lustre modules and userspace are built.
-
-  --lustre=LUSTRE
-    Path to an existing lustre source tarball to use instead of
-    pulling from CVS.
-
-  --nodownload
-    Do not try to download a kernel from ftp.lustre.org
-
-  --nosrc
-    Do not build a .src.rpm, a full kernel patch, or a patched kernel
-    tarball.
-
-  --publish
-    Unused.
-
-  --release
-    Specifies that the files generated do not include timestamps, and
-    that this is an official release.
-
-  --src
-    Build a .src.rpm, a full kernel patch, and a patched kernel tarball.
-
-  --stage=DIR
-    Directory used to stage packages for release.  RPMs will be placed
-    more or less in DIR/<target>-<arch>, and the tarball will be
-    placed in DIR.
-
-  --tag=TAG
-    A CVS branch/tag name to build from when pulling from CVS.
-
-  --target=TARGET
-    The name of the target to build.  The available targets are listed
-    below.
-
-  --target-archs=TARGET_ARCHS
-    A (space delimited) list of architectures to build.  By default,
-    all of the archs supported by the TARGET will be built, in
-    addition to a .src.rpm.  This option can limit those, for machines
-    that can only build certain archs or if you only want a certain
-    arch built (for testing, or a one-off kernel).
-
-    Also note that by using a non-"base" arch (eg, i386) only kernels
-    will be built - there will be no lustre-lite-utils package.
-
-  --disable-datestamp
-    Prevents the datestamp flag (-D) from being passed to cvs for 
-    checkouts. This is a workaround for a problem encountered when 
-    using lbuild with tinderbox.
