The value is captured when you run GYP, not when you build. Is that what you
expect?

I think it should be fine for print_version.py to run at GYP generation time. I
can't think of a reasonable case where you'd want to publish docs but have
synced to a newer version without executing "gclient runhooks" 
I don't really know gyp that well. I'm assuming that when you run "gclient
runhooks", the python script will run even if none of the listed dependencies or
inputs have changed. 

[ahe, 2013/02/11 07:27:56]

Correct. This is why we shouldn't list list_version.py as a dependency. It isn't
used at build time.

I think I spotted a problem here. We are not listing the contents of the
../../pkg. You should probably include that in line 35 above.

[Jacob, 2013/02/11 01:44:11]

Interesting but unrelated to this cl. I'll follow up separately with the pub
team to see if we are specifying the wrong pkg directory.
