doc: there is no images/*cpio or images/*jffs2

within build scripts, to respect our users' security concerns.
The script creates three output files, that can be used in different
situations, like @i{initramfs} or unpacking for NFS-Root. All of them
are around 15MB of data, and the flashing script only uses the first
listed here:
The script creates an archive for the whole filesystem,
called @t{wrs-image.tar.gz}. It is used by the installation
procedure and it is ready to be unpacked for NFS-Root. It is currently
slightly less than 20MB of data.

@item wrs-image.jffs2.img
This is a raw image in JFFS2 format, which is ready to be
written to NAND flash. This is used bt the USB flasher.
@item wrs-image.cpio.gz
If you prefer to run an @i{initramfs} system, this is the file
you should use. We used it a lot during development, to avoid
wearing the flash device and wasting time waiting for the flasher
to run.
@item wrs-image.tar.gz
We added this out of laziness, because it's easier to create
your NFS-Root directory from @i{tar} than from @i{cpio}.

You can uncompress either @i{cpio} or @i{tar}, for example to run NFS-root,
by running one of the following commands in a newly-created empty directory:
