Looks like the mods changed the title I gave. Just for those that don't know, "n" is a version manager for Node.JS that some use to handle multiple copies of Node.JS on their system.
"Running and stable with no bin, lib, share, include directories in /usr/local".
Which didn't seem all that exciting to me, so I clicked just to see what all the excitement was with not having a /usr/local.
PS. "n" is a terrible name for a program - it's impossible to google.
