README: py-smbus

Prerequisites:
Be sure to build and install the lm-sensors userspace first.  This package
requires one of the header files from that.

To build:
	$ python setup.py build

To install (will also build if necessary):
	$ python setup.py install

For general build/install help:
	$ python setup.py --help-commands

Frequently Answered Question:

Q: It's throwing exceptions, nothing works, what's wrong?

  A1: You need write permissions to the i2c-dev devices.  Try running as root.

  A2: Addresses in Linux/I2C are the most-sig 7 bits, right-justified.  E.g.
	if your device uses address 0xc0 to write and 0xc1 to read, then use
	address 0x60 with this module.

  A3: Some other kernel driver has claimed that I2C address.  Unload it first.
