-# Strings
-
-This module provides a few basic utilities to manipulate strings.
-
-## Usage
-
-### pad
-
-Input string is processed to output a string with a minimal length. If the
-parameter `strict` is set to true, the output string length is equal to the
-`strLen` parameter.
-
-Basic usage:
-
-```ts
-import { pad } from "https://deno.land/std/strings/pad.ts";
-pad("deno", 6, { char: "*", side: "left" }); // output : "**deno"
-pad("deno", 6, { char: "*", side: "right" }); // output : "deno**"
-pad("denosorusrex", 6, {
-  char: "*",
-  side: "left",
-  strict: true,
-  strictSide: "right",
-  strictChar: "...",
-}); // output : "den..."
-```
