We should jump on a phone call to clarify this tomorrow. I am not sure I fully understand this though the gist sounds right. I am free tomorrow at 2 my time if you are. Right now, if you specify R13B, for example, it > overwrites it to where the erts version should be.

I agree though that this should be moved from there to a config file. You should start with that .hrl file and grep for the usage of that macro so you can get familiar with what functionality has been put in place already. > > On 27 Nov, 11:53, Zishan Mirza <[email protected]> wrote: >> This sounds good.
