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 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.
Yeah, Google doesn’t care for punctuation of any kind really.
$. is used to denote the load path for Ruby libraries, so the line that
have there is to prepend the lib/ directory, which is a peer to the
directory your script is in, to the front of the load path.
FYI, it’s aliased as $LOAD_PATH in case you want to change it for better
