A rule for importing .whl dependencies into Bazel.
This rule is currently used to implement pip_import. It is not intended to work standalone, and the interface may change. See pip_import for proper usage.
This rule imports a .whl file as a py_library:
whl_library( name = "foo", whl = ":my-whl-file", requirements = "name of pip_import rule", )
This rule defines @foo//:pkg as a py_library target.
