# DP: Allow hwcap's to be disabled with the existence of a file. This
# DP: makes it easier to do upgrades with optimized (hwcap) library
# DP: packages.
# DP: Author: Rewritten by Daniel Jacobowitz <dan@debian.org>
# DP: Upstream status: Debian-Specific
# DP: Status Details: This isn't going to be acceptable upstream, we
# DP:                 only need it because we support in-place upgrades.
# DP: Date: 2003-10-28, (Updated 2005-01-02 gotom, 2007-05-20 aurel32)
