+Creates a logical collection of Starlark .bzl and .scl files.
+
+Example:
+  Suppose your project has the following structure:
+
+  ```
+  [workspace]/
+      WORKSPACE
+      BUILD
+      checkstyle/
+          BUILD
+          checkstyle.bzl
+      lua/
+          BUILD
+          lua.bzl
+          luarocks.bzl
+  ```
+
+  In this case, you can have `bzl_library` targets in `checkstyle/BUILD` and
+  `lua/BUILD`:
+
+  `checkstyle/BUILD`:
+
+  ```python
+  load("@bazel_skylib//:bzl_library.bzl", "bzl_library")
+
+  bzl_library(
+      name = "checkstyle-rules",
+      srcs = ["checkstyle.bzl"],
+  )
+  ```
+
+  `lua/BUILD`:
+
+  ```python
+  load("@bazel_skylib//:bzl_library.bzl", "bzl_library")
+
+  bzl_library(
+      name = "lua-rules",
+      srcs = [
+          "lua.bzl",
+          "luarocks.bzl",
