if you see naming a tool with a clever play on the command "man" as perpetuating a "boys only" culture you almost certainly need more human-to-human interaction away from the computer and away from tumblr or whatever terrible place has brainwashed you.
If this tool was invented 20 years ago, before the whole brogrammer thing took over the term bro, everyone would have thought it was a clever play on man pages. Seems the word bro itself has become offensive, even if used in a non-offensive context.
