asterisk users - Aug 2014 - How to master Asterisk version when cloning PJPROJECT ?

Hello,

I'm giving Asterisk 12 and 13 my first try.

When compiling PJPROJECT from source, as described in wiki page, I'm using
this:
        git clone https://github.com/asterisk/pjproject pjproject

I suppose the above PJPROJECT is evolving for Asterisk 12, Asterisk 13
and later.
A quick look at https://github.com/asterisk/pjproject shows several tags.

I want to be able to build a bit-to-bit exact copy of given setup,
several months later.

How can I achieve this ?
Is it possible to specify with git the exact Asterisk version I would
like PJPROJECT to match ?

Regards

This is actually unlikely. PJPROJECT itself is an outside project[1]. A 
version exists in git by us because we added shared library support to 
it (which is now upstream). The git repo exists for now in case we need 
to make any other large changes. It may go away in the future and the 
instructions updated to just use pjproject from upstream.

I'd just use a specific released version of pjproject. I personally use 
the SVN version of pjproject to ensure that Asterisk can compile against 
it at all times. Provided you use the 2.x series then it's fine.
