# Doing a make install builds /usr/include
#
# Define SHARED to indicate whether you want symbolic links to the
# system source (``symlinks''), or a separate copy (``copies'');
# (latter useful in environments where it's not possible to keep
# /sys publicly readable)
#
# The ``rm -rf''s used below are safe because rm doesn't follow
# symbolic links.
