Jérôme, All,
On 2016-03-08 22:48 +0100, Jérôme Pouiller spake thusly:
> It is handy to use local.mk or external.mk to add specific targets
> for current project. However, until now, it not possible to add help
> message these targets.
Another implementation has been applied:
https://git.buildroot.org/buildroot/commit/?id=84c825f8e893bfb56847ab4a880c46066a41744f
Consequently, I've marked your patches as rejected in patchwork.
Thanks for starting up the discussion! :-)
(Note: Thomas applied my implementation by accident, but later decided
not to revert it. There are still a few issues, which your proposal also
had, and we're fixing them now.)
Regards,
Yann E. MORIN.

> EXTRA_HELP += "`printf '%-22s%s' '$(var)-feature' ' - Call $(var) feature'`"
> EXTRA_HELP += "Please contact support at company.com in case of problem."
