dnu restore --quiet now outputs numerous lines like

*** READING C:\Users\dougbu\.dnx\packages\System.Linq.Expressions\4.0.11-beta-23302\runtime.json

What do these messages mean? Since there does not appear to be an action users can take in response, suggest removing the lines from the dnu restore output (not just from the --quiet output).

These messages do not just appear for System.Linq.Expressions though that is by far the most commonly-mentioned package, at least when in the Mvc repo.
