// import-boss enforces import restrictions in a given repository.
//
// When a directory is verified, import-boss looks for a file called
// ".import-restrictions". If this file is not found, parent directories will be
// recursively searched.
//
// If an ".import-restrictions" file is found, then all imports of the package
// are checked against each "rule" in the file. A rule consists of three parts:
// * A SelectorRegexp, to select the import paths that the rule applies to.
// * A list of AllowedPrefixes
// * A list of ForbiddenPrefixes
// An import is allowed if it matches at least one allowed prefix and does not
// match any forbidden prefix. An example file looks like this:
//
// {
// "Rules": [
// {
// "SelectorRegexp": "k8s[.]io",
// "AllowedPrefixes": [
// "k8s.io/gengo/examples",
// "k8s.io/kubernetes/third_party"
// ],
// "ForbiddenPrefixes": [
// "k8s.io/kubernetes/pkg/third_party/deprecated"
// ]
// },
// {
// "SelectorRegexp": "^unsafe$",
// "AllowedPrefixes": [
// ],
// "ForbiddenPrefixes": [
// ""
// ]
// }
// ]
// }
//
// Note the second block explicitly matches the unsafe package, and forbids it
// ("" is a prefix of everything).
