How is the commented out require still working

Question

I was encountering a cofeescript page, when i happened to bump into a require syntax like #= require something It is not a commented out required syntax, and removing the = breaks the build. The project seems to be using angular, with coffee script , connect assets and jade. here is the link to one of the files. can anybody explain me what is happening in here?

Answer 1

found out that this is a rack based package management system that comes shipped with connect-assets
