[chef] Altering override_attributes via command line?

[howard chen < >]

Hi,

I am using chef-solo using the command like,

    # chef-solo -c ~/solo.rb -j ~/node.json

The `override_attributes` is defined in the node.json, but sometimes
it would be handy to change the value from the command line instead of
editing the file.

Is it possible?

Thanks.
