-;;; bytes.el --- Working with byte values -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "24.3"))
-
-;;; Commentary:
-;; Functions to help with human-readable representations of byte values.
-;;
-;; Usage:
-;; See the test cases for example usage.  Or better yet, I should use a type of
-;; structured documentation that would allow me to expose a view into the test
-;; suite here.  Is this currently possible in Elisp?
-;;
-;; API:
-;; - serialize :: Integer -> String
-;;
-;; Wish list:
-;; - Rounding: e.g. (bytes (* 1024 1.7)) => "2KB"
-
-;;; Code:
-
-;; TODO: Support -ibabyte variants like Gibibyte (GiB).
-
-;; Ranges:
-;;  B: [   0,  1e3)
-;; KB: [ 1e3,  1e6)
-;; MB: [ 1e6,  1e6)
-;; GB: [ 1e9, 1e12)
-;; TB: [1e12, 1e15)
-;; PB: [1e15, 1e18)
-;;
-;; Note: I'm currently not support exabytes because that causes the integer to
-;;  overflow.  I imagine a larger integer type may exist, but for now, I'll
-;;  treat this as a YAGNI.
