Handy hacky script to help me reorganize a flask project

autotree.py

import envoy, time, os

def main():
    old = ""
    time.sleep(1)
    while True:
        new_run = envoy.run("tree -I \"init|*.pyc|*html\" --noreport -L 3 -F")
        new = new_run.std_out
        if old != new:
            envoy.run('clear')
            old = new
            print old


if __name__ == '__main__':
    main()
