    command = 'bash',
    args = { '-c', 'echo "Doing The Thing"'},

- This uses ` BufWritePost [TODO: Code shorthand span ] to pickup when files are saved and then runs whatever is in the callback

- I tried ` callback = do _ the _ thing() [TODO: Code shorthand span ] directly but it didn't work without the wrapper ` function() ` lua `

- This runs the command asycn and prints the response when it finishes

- There's no error handling in this example, that would depend on the response in ` on _ exit ` lua `

- TBD on accessing STDERR from on _ exit
