Edit Question
Title
Body
I found this in Gemspec file of surveyor gem . What does the following line do? $:.push File.expand_path("../lib", __FILE__) require "surveyor/version" Why does the $:.push thing do? To me it looks like its just requires the ../lib/surveyor/version file. if so, can't I just replace that with following one line? require File.expand_path('../lib/surveyor/version', __FILE__) Are both these same thing? If not, then what the difference?
