-This directory is used by the libguestfs 'virt-builder' to store the
-clean, signed OS templates used for building new virtual machines.
-
-The index file is the default source URL and links to the other OS
-templates.  It has the canonical URL:
-
-  http://libguestfs.org/download/builder/index.asc
-
-If you are looking at this file in the git repository
------------------------------------------------------
-
-libguestfs.git/builder/templates/ contains the program used to
-generate the template files, the source for the index, kickstart files
-and more.
-
-When you use the ./run script to run virt-builder without installing,
-the ./run script sets $VIRT_BUILDER_SOURCE to point to this directory.
-If you actually want to use this configuration for anything except
-simple testing, you will have to download one or more OS templates
-from the libguestfs website and put them into this directory.
-
-ie:
-
-  ./run virt-builder fedora-20
-
-will fail unless you have downloaded fedora-20.xz here.

-The general plan for using kickstart and virt-install is outlined
-by Kashyap here:
-
-http://kashyapc.wordpress.com/2011/08/18/unattended-guest-install-with-a-local-kickstart/
-
-If you want to reproduce the builds then the kickstart files are
-located in fedora-<N>.ks and the virt-install + other commands are in
-fedora-<N>.sh.
