README.directories contains a description of the directories I created; read it if you have questions about them. doc/design is the design document I sent before through email. doc/useful_addresses.html contains links to I2C, SMBus and sensors information. Note that we may have to change minor i2c things, like Makefiles; this is why I put it in the archive too (we should, of course, send important changes to Simon Vogl). git-svn-id: http://lm-sensors.org/svn/lm-sensors/trunk@3 7894878c-1315-0410-8ee3-d5d059ff63e0
