add copyright notice to commands
eliminate/reorganize imports to speed up start time:

0.5b:
$ time bash -c 'for i in `seq 100`; do ~/bin/hg > /dev/null; done'

real    0m7.718s
user    0m6.719s
sys     0m0.794s

new:

$ time bash -c 'for i in `seq 100`; do hg > /dev/null; done' 
real    0m2.171s
user    0m1.684s
sys     0m0.444s

just python:

$ time bash -c 'for i in `seq 100`; do python -c pass; done' 
real    0m0.988s
user    0m0.771s
sys     0m0.207s

Ignoring the fixed cost of loading the Python interpreter, we're 5.6
times faster. With the Python load time, we're still 3.5 times faster.
