    Well, just like the other stuff in the prog directory. It's just a
sample program utilizing i2c bus. It's not a complete solution & will never
be, but treat as decoding software. In fact, it's possible to make it a
sensors like kernel module.

    Exactly. But also they're too small to make them separate package, but
very handy.

    I'd rather suggest to make separate package for the lm_sensors, called
i2c-utils or something like this and include existing progs. Or,
alternatively you can make a registry of existing projects, utilizing I2C
bus. In fact, there are number of packages which use i2c, but due to their
size and specific they are never become well known to public, except the
ones which is already included to the lm_sensors package.

Thank you for explanations,
