Tried to look into #rgrep in #emacs to capture two terms, and I still don't get it. The manual seems to list all the #grep commands in emacs but there aren't a lot of examples as to how to use them. It says to use grep as you'd use it in the shell, but I can't pipe grep the same way (unless I use shell inside emacs, which is not the point).
So, any good rgrep examples out there?
