# 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.
