This package contains command line utilities for interacting with
XenStore.

XenStore is a shared database used for interdomain communication of
configuration and status information. It is accessible to all domains
running on the same Xen host. See https://wiki.xen.org/wiki/XenStore for
more information.

In the common case these tools are used by the Xen toolstack running in
domain0 (or a driver domain) however they may also be used in a guest
domain to support local scripting which wants to communicate via XenStore.
