man++

Go in a web browswer and type "man something" and you should usually get the unix man page for the command "something" as the first match.

man++ : be able to type something like "man mount -tjffs2" and you get

mount - mount a filesystem

-tjffs2 : inferred to mean vfstype is "jffs2"



You get the idea. User came looking to find out what an option means. You save him the pain of reading the whole man page to find out what a particular option, or options mean..
