-# ngc-wrapped
-
-This is a wrapper around @angular/compiler-cli that makes ngc run under Bazel.
-It should be identical to https://github.com/bazelbuild/rules_angular/tree/master/internal/ngc
-however that is built against Angular packages from npm, while ngc-wrapped is
-built using Bazel against Angular at HEAD.
