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 you 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 clarity.
