I slashed at the Edit page.
I just spent 10 minutes scratching my head over the behavior of play. I couldn't get the -f flag to work-- could only play a file when I omitted the flag and just used play <my_file>. I'd change the wiki myself but I'm not sure if play -f works in any context.
@smackesey, there is no play -f in Pry v0.9.12.1.
We need to update, like, everything.
