Re: [Monotone-devel] newbie question - SHA1 vs serials

I'm sorry, I don't understand how your answer below relates to
*avoiding* branches.  (It does nicely answer my question of what branch
support you would like in your SCM tool; thanks ;)

Can you clarify at all what sort of support an SCM could give you to let
you have > 128 concurrent developers on one branch all churning a given
file?

thanks,
