#!/bin/bash

# Invoke like this:
# ./watch.sh my command here
# And it will run 'my command here' once, and then when it detects changes.

# TODO: Don't just search in the last second. Search for updates since the last
# completed build. Otherwise for big directories, midway through your search
# you've already taken 1s and you will miss updates.
