For reading user input from stdin.
Similar to the
question() method, but with a
few more features.

The callback gets called with either the user input, or the default
specified, or an error, as

Every option is optional.

This module works sort of with node 0.6. It does not work with node versions less than 0.6. It is best on node 0.8.
On node version 0.6, it will remove all listeners on the input
keypress events, because the readline module did
not fully clean up after itself in that version of node, and did not
make it possible to clean up after it in a way that has no potential
for side effects.
Additionally, some of the readline options (like
terminal) will not
function in versions of node before 0.8, because they were not
implemented in the builtin readline module.
