This package defines some macros that you can use in your Emacs configuration to evaluate certain settings only on specific operating systems or specific hosts. All the relevant macros are autoloaded, so if you install this through package.el, you can just use them in your initialization file. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
