 Let's say that we have a pet peeve: people who use `tmp` as a temporary filename. We want to warn about statements like `sort file > tmp && mv tmp file`, and suggest using `mktemp` instead.
 
-We can start by looking at the AST for `sort file > tmp`. In a ShellCheck source directory, run `cabal build` to generate necessary files, then run `ghci ShellCheck/Parser.hs`:

 This has given us a REPL where we can call parsing functions. There's a convenient `debugParseScript` function that will take a string and give the complete parser result (minus noisy token positions):
