It's exactly the same.

The kconfig-frontends package is created by extracting the needed files from
the linux kernel. So, kconfig-diff is exactly scripts/diffconfig. Also, it's
what the line just above says: "added _from_ the Linux kernel tree" ;-)

But the kconfig toolss in the linux tree are not using a common naming
scheme. For example we have:
    scripts/config
    scripts/diffconfig
    scripts/kconfig/merge_config.sh
    scripts/kconfig/kxgettext
    scripts/kconfig/conf
    scripts/kconfig/mconf

So, kconfig-frontends tries to use a meaningful naming scheme for all the
programs it installs. Some are renamed, and they all get prefixed by default
with 'kconfig-' (although that can be overriden at ./configure time with
--program-prefix=...).

In the package, the file scripts/kernel2kfrontends.list has the
correspondence for what comes from the linux tree, and how it's named in
the kconfig-frontends tree. For example, we have:
    scripts/config                      -->  utils/tweak
    scripts/diffconfig                  -->  utils/diff
    scripts/kconfig/merge_config.sh     -->  utils/merge
    scripts/kconfig/kxgettext.c         -->  utils/gettext.c

The script scripts/ksync.sh (in kconfig-frontends) uses that file to
automatically sync from a linux tree.

There is virtually zero code written in the package (except for a few patches
required for the packaging), so the behavior is exactly the same as if using
the corresponding kconfig tools from the kernel.

Please note, however, that this is only the second release of
kconfig-frontends, and that things can still be improved upon! ;-)

Yann E. MORIN.
