From 9f4e5b4aca897841e42001af85e59fb109f9de3e Mon Sep 17 00:00:00 2001
From: P. J. McDermott <pjm@nac.net>
Date: Thu, 08 Nov 2012 01:36:25 -0500
Subject: Update build.

  * Use new features of opkhelper; don't use obsolete oh-* utilities.
  * Clean up code according to best practices and SPF 2.0
    recommendations.
  * Read target architectures from generated configuration file.
  * Add a "clean" target for convenience.

The "install" target has yet to be updated.
