Are your gems taking up too much disk space? Documentation got you down? Comments stuck in your craw? Tests taking too much space? Fix all that by with gem tldr. I know that disk space is at a premium these days with an introductory netbook or a small AWS EC2 instance containing a mere 160GB. gem tldr removes the test directory, build artifacts like .c and .h files, comments in your ruby source files and comments in your ruby source.
