package(default_visibility = ["//visibility:public"])
filegroup(
    name = "file",
    srcs = glob(["*"]),
    visibility = ["//visibility:public"],
)
        """
        sha256 = "56e7256bef10fc2a30c5c287c54ae95312608c56a3fd7917e3a5708f32198fce",
        urls = ["https://github.com/linkerd/linkerd2/archive/refs/tags/{version}.tar.gz".format(
            version = VERSION,
        )],
    )

go_library(
    name = "example",
    srcs = ["main.go"],
    embedsrcs = ["@manifests//:file"],  # keep
    importpath = "...",
    visibility = ["//visibility:public"],
)

main.go attempts to embed the files downloaded //go:embed all:*.
