# If an include file is already installed, this always compares the
# installed file to the one we are about to install. If they are the
# same, it doesn't do the install. This is to avoid triggering massive
# amounts of rebuilding.
#
# Targets:
#
# includes:
#	Installs the include files in BUILDDIR if we are using one, DESTDIR
#	otherwise. This is to be run before `make depend' or `make'.
#
# install:
#	Installs the include files in DESTDIR.
