As a person that does a lot of software packaging (RPM for all our Unix
platforms), it's nice to see a package that doesn't make using a temporary
install destination ( a BuildRoot, in RPM-speak) a pain.

The one that works the best (IMHO) is the one that's used by much of X11
and by automake: stick a
DESTDIR =
somewhere in the Makefile.in (this is done for you automatically by automake)
and then prefix all destination directories in the install target(s) with
$(DESTDIR), i.e.:
install : foo foo.1
$(INSTALL_CMD) foo $(DESTDIR)$(bindir)
$(INSTALL_DATA) foo.1 $(DESTDIR)$(man1dir)
That way, someone doing packaging can do
./configure --prefix=/whereever --exec-prefix=/someplaceelse
make
make DESTDIR=/tmp/build/foo install
and everything ends up in /tmp/build/foo for packaging. This works really
well.
