| We currently pull zlib from a pagespeed git mirror, however there's a there's | |
| a perfectly fine zlib repo at https://github.com/madler/zlib.git. | |
| We should copy the gyp file out of the zlib repo and into the mod_pagespeed | |
| one, after which we can switch to the official zlib repo and delete | |
| https://github.com/pagespeed/zlib. |
