  Hello,

  one more thing - should we keep the $COPTS variable? Most projects
(including Cogito) have the C flags controlled by the $CFLAGS variable.

  What I would propose:

	-COPTS=-g -O2
	-CFLAGS=$(COPTS) -Wall
	+CFLAGS?=-g -O2
	+CFLAGS+=-Wall

  That is, if user does not specify custom $CFLAGS, default to "-g -O2",
and always append -Wall (and more after I'll send my Makefile patches).

  Opinions?

Sounds good. I've never heard of anyone using COPTS variable before. And
"-g -O2" seems to be a good default value.

Using $DESTDIR instead of $dest would be nice too because DESTDIR is used
by Autotools.
