Hello,
the attached patch adds Xenomai configuration help for Linux 2.4:
2006-11-11 Wolfgang Grandegger <wg@domain.hid>
* scripts/prepare_kernel.sh, scripts/help_from_kconfig.pl:
prepare_kernel.sh will now add help for Xenomai configuration
parameters to the Configure.help file of 2.4 kernels. The help
is extracted from Xenomai's Kconfig files using a perl script.
Wolfgang.

Cool that you picked this up! Frankly, I didn't expect that this would
really work without any pitfalls - but it seems to.
Just one addition feature wish: Could you enhance it so that it can also
upgrade an existing Configure.help patch? Maybe put some magic marks
(comments) around the xeno stuff and remove the whole block before
re-patching the help information?
Thanks,
Jan (who wishes that this would also work for Kconfig->Config.in...)

I immediately liked you idea. Having an easily accessible description of
the Xenomai kernel configuration parameters helps users a lot. So far I
just realized some problems with "choice" but they seem not related to
the conversion. It's more likely a bug in menuconfig.

You mean re-running "prepare-kernel" should update the Xenomai block in
Configure.help? Doing it in the perl script should not be a big deal.

Yeah, but...
Wolfgang.

I think the attached patch does what you want (using sed).
