Merge lp:~james-w/linaro-image-tools/debug into lp:linaro-image-tools/11.11

[James Westby]

Hi,

This adds some output as the tool is running, and also adds a --debug
option that we can add more info to.

Thanks,

James

Seems basically fine. I'm a bit confused as to what is INFO and what is DEBUG. Would it make sense to have things that happen once per run at INFO and once per package at DEBUG? But I guess it's not that important.

Yeah, I just made some simple ones INFO. I'll spend a few minutes
thinking about the desired output and add that as INFO, and leave the
rest as DEBUG.

Thanks,
