+ * # deno-mkdirp
+ *
+ * `mkdir -p` 4 `deno`.
+ *
+ * ## Import
+ *
+ * ```ts
+ * import { mkdirp } from "https://deno.land/x/std/fs/mkdirp.ts";
+ * ```
+ *
+ * ## API
+ *
+ * Same as [`deno.mkdir`](https://deno.land/typedoc/index.html#mkdir).
+ *
+ * ### `mkdirp(path: string, mode?: number) : Promise<void>`
+ *
+ * Creates directories if they do not already exist and makes parent directories as needed.
