package_info
The package_key is most trickiest part of this command: You must prepend a main language of the library just before product's id. It's required to prevent ambiguity between packages with same name.
For example, if you have Java package with product id junit/junit, then you have to encode this value as: java/junit/junit.
$> veye info java/junit/junit
Asking information about: junit/junit
