[Buildroot] [PATCH 1/1] Add proxy download support

[Yann E. MORIN]

Karoly, All,

On 2014-10-21 16:53 +0200, Karoly Kasza spake thusly:
> This patch adds support for downloading sources over a http proxy.
> Supports wget with http, https & ftp targets, bzr, hg, svn.
> Git does work with forcing https instead of git protocol.
> Cvs is not supported, but Buildroot does not currently have any
> packages relying on cvs repos (plus this would fall back to the
> Buildroot mirror over http).
> 
> Signed-off-by: Karoly Kasza <kaszak at gmail.com>

After speaking with Peter, and given the feedback from both Arnout and
I, we believe this belongs to the user's settings, and has no place in
Buildroot.

So, I've marked this patch as Rejected in patchwork.

Regards,
Yann E. MORIN.
