[erlang-questions] Makefile detecting / downloading rebar

[Dmitry Kolesnikov]

Hello,

Yes, I am using same approach with an exception I am ignoring a global rebar installation.
just keep in mind that wget might not be present. It should be possible to choose between curl & wget. I believe distclean target should also remove downloaded rebar.
