If you google/duckduck go something more than once, I think it should be put into documentation. I have one central org file where I keep that majority of my one off questions about a tool, and these days I look there often first before man or info because I have condensed the information into something faster to parse for me.

Right now my main battle is deciding to port docs like this into asciddoc(tor) or keep them in org, both being exported to html5 eventually.
