xen-clone

usage: xen-clone <bk_repository> <dest_dir> <orig_linux_dir>

This script can be used to 'bk clone' and build a xen and xenolinux image 
from the master BK repository, either from a local copy, or from the
public repository bk://xen.bkbits.net/xeno.bk

In many circumstances, it can be invoked without any arguments and
just `does the right thing'.

The default dest_dir is 'xeno-clone', relative to the current directory.

To build xenolinux, the script needs a pristine copy of the equivalent 
linux tree. The script looks in a couple of places on the local filesystem, 
then tries a download from from ftp://ftp.kernel.org/pub/linux/kernel/v2.4/

The script also tries a number of optional UCCL site-specific operations
that configure the test machine booting infrastructure to boot the 
resultant image.
