+;;; Commentary:
+;;
+;; Keeping track of rapidly developing software is a tough thing to
+;; do, especially if you want to have co-dependent packages which all
+;; move at different rates.
+;;
+;; This library provides a framework for specifying version numbers
+;; and (as side effect) have a flexible way of getting a desired feature set.
+;;
+;; If you would like to use this package to satisfy dependency replace this:
+;;
+;; (require 'spiffy)
+;;
+;; with this:
+;;
+;; (require 'inversion)
+;; (inversion-require 'spiffy "1.0")
+;;
+;; If you feel the need to not throw errors, you can do this instead:
+;;
+;; (let ((err (inversion-test 'spiffy "1.0")))
+;; (if err (your-stuff-here)))
+;;
+;; If you new package (2.0) needs to make sure a load file from your
+;; package is compatible, use this test:
+;;
+;; (if (not (inversion-reverse-test 'spiffy version-from-file))
+;; ;; Everything ok
+;; (do stuff)
+;; ;; Out of date
+;; (import-old-code))
+;;
+;; If you would like to make inversion optional, do this:
+;;
+;; (or (require 'inversion nil t)
+;; (defun inversion-test (p v)
+;; (string= v (symbol-value
+;; (intern-soft (concat (symbol-string p) "-version"))))))
+;;
+;; Or modify to specify `inversion-require' instead.

+;;
+;;
+;; `pulse-momentary-highlight-one-line' - Pulse a single line at POINT.
+;; `pulse-momentary-highlight-region' - Pulse a region.
+;; `pulse-momentary-highlight-overlay' - Pulse an overlay
+;; These three functions will just blink the specified area if
