  • It means that whoever wrote this doesn't understand `require_relative` and shouldn't be allowed to write Ruby code. – Jörg W Mittag Apr 08 '17 at 07:25

$LOAD_PATH is an array. Try running $LOAD_PATH.class in irb to prove it to yourself. The unshift method of Array adds something to the beginning of the array. https://ruby-doc.org/core-2.2.0/Array.html#method-i-unshift

In this case, it adds the absolute path of the ruby file, up three directories, then down into lib. https://ruby-doc.org/core-2.2.0/File.html#method-c-expand_path
