From e320fe3db8ddb316eeb5e68e9af9aef75dd71628 Mon Sep 17 00:00:00 2001
From: Oliver Schmidt <ol.sc@web.de>

Subject: [PATCH] Added 'install' target.

The 'install' target primarily aims to support pacaking tools. Therefore...
- It just presumes a "capable" install program to be present.
- There's intentionally no 'uninstall' target.
