To install this package, run in Emacs:
M-x package-install RET use-package RET
The `use-package' declaration macro allows you to isolate package configuration in your init file in a way that is performance-oriented and, well, just tidy. I created it because I have over 80 packages that I use in Emacs, and things were getting difficult to manage. Yet with this utility my total load time is just under 1 second, with no loss of functionality! See the `use-package' info manual for more information.
