[erlang-questions] predefined Erlang version macros

[Joseph Wayne Norton]

Stefan -

I typically use macros with rebar's platform_define feature for such situations.

Here is an example for R14 and old inets behavior (https://github.com/ubf/ubf-jsonrpc/blob/master/rebar.config#L6).

This method is simple but works only at compile-time.

Regards,

Joe N.
