[PATCH] Update the information in README about using the library.

[Franz Schrober <franzschrober@gmail.com>]

From: James Westby <james@jameswestby.net>

Changes in the library have left the README giving out of date information
on how to intialise the library and get the symbols out of it. Update the
documentation to match the latest functions.

This patch was already submitted by James Westby and had to be reverted again
after he didn't responded in the 4 year relicense process. Now he accepted the
change to MIT license and I just resubmit it for him. So it is a revert for the
revert 01b00f59f2a6aba6b623c0a68827938c1f570877 ('Revert "Update the
information in README about using the library."')

Sorry for the inconveniences.

 This means that a user of the library will literally just need to do
