[Nix-dev] NIX_BUILD_HOOK documentation

[Rickard Nilsson]

Hi,

I was looking for the documentation for NIX_BUILD_HOOK, but it seems to  
have been commented out in  
https://github.com/NixOS/nix/commit/7a213ffc6912794d2cc4374bb9bf2c1f59a384a3  
. Why is that? Has the NIX_BUILD_HOOK protocol changed? My aim is to write  
my own build hook, should I wait for updated documentation or follow the  
existing (commented out) documentation?
