How to ring the bell from the terminal.

Printing "\a" from bash, Python, and most other languages will ring the bell. It's almost trivial, but a good (if annoying) way to communicate with the user.

For example, when developing Siafoo we run unittests occasionally, these could take a while or crash right away, and I don't want to sit and stare at them:

# 's
1nosetests -x [some other options]; echo $'\a'

Now I can tell audibly when the tests are done.... granted I can also tell when my laptop stops sounding like a jet engine, but that's a bit more delayed...
