Regarding modified hello world example

[Tanu Hari Dixit]

Hello Devs,

Kindly advise me whether I need to send a patch with a modified hello
world example as given in
https://devel.rtems.org/wiki/GSoC/GettingStarted#ProveYouCanWorkOnRTEMS.
Furthermore, I wanted to ask, is there a new set of documentation that
I should be aware of, other than that hosted at
https://devel.rtems.org/ ?
I aim to participate in GSoC '17 under RTEMS. How should I proceed
now, that I have set up RTEMS ?
Also, when I modified testsuites/samples/hello/init.c, the following
m4 files also got modified:

  c/src/lib/libbsp/bfin/acinclude.m4
  c/src/lib/libbsp/powerpc/acinclude.m4

in the following way,

diff --git a/c/src/lib/libbsp/bfin/acinclude.m4 b/c/src/lib/libbsp/bfin/acinclud

Should I be worried about these? Why did the order of the subdir change here?
