Stuff worth explaining
======================
.bash_prompt
~~~~~~~~~~~~
This file provides ``prompt_command`` function that is executed by the 
shell just before displaying ``PS1`` (which the function sets). The result is a
colored shell prompt.
Note that the clock is not real-time. It updates after your shell command 
finishes (e.g. after you press enter). That's sufficient if you want to 
know how long your db backup took, for example.

Mercurial and Git support is disabled for root, thus two colored dashes.
.bash_aliases
~~~~~~~~~~~~~
This file contains aliases. Currently, the only alias that is not exactly 
self-explanatory is ``whatsopen``. In short, it's an alternative to 
``sockstat`` from FreeBSD. It shows listening (TCP) applications, like 
``netstat -ntlp``, but with a handy difference. It additionally shows 
users, so instead of this::
    Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
    tcp        0      0 127.0.0.1:5984          0.0.0.0:*               LISTEN      30617/beam.smp      
you get this::
    COMMAND     PID    USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
    beam.smp  30617 couchdb   16u  IPv4 7652760      0t0  TCP 127.0.0.1:5984 (LISTEN)
See? It's much easier to guess what beam.smp is when you know couchdb owns 
it. And it's much, much easier to understand what python2 is doing there 
when its owner is my-django-site-user or something.
