I couldn't use this, needs better error messages, and or a tutorial

[paulsonkoly]

Here's the terminal session I had with visual-prof. I believe it needs better error handling, and a tutorial about how to use it. Also I would put up a sample about what it creates, so ppl could decide whether they want this or something else..

✓ phaul codewars $visual-prof --help
visual-prof: mode should be -h or -px
✗ 1 phaul codewars $ visual-prof -h
visual-prof: Prelude.(!!): index too large
✗ 1 phaul codewars $ visual-prof -px Main.hs dist/build/codewars/codewars
