I have a script with the first line as follows:
$:.unshift(File.dirname(__FILE__) + '/../lib')
This must mean something nasty to Google, because I can't seem to get anything useful if I include it in a search string, even quoted. Ditto stackoverflow and rubytips.
Having this line at the beginning of this script seems to treat the require <gem name> statements that follow it differently than a normal require would, or at least I am not getting the same errors as I do when I require the gems without this line.
What does it do?
