    I can give your more information about make if you want.  I use
emacs and make as my development environment for all of my AVR
development under FreeBSD and Linux.  It works great for me.  I have a
template Makefile that I always use, modifying it for a new project is
basically a one line change.  This Makefile was included in an example
directory under one of the WinAVR releases actually.
    All you need to do to start a new project using this Makefile is
put the name of your main program file (with no extension) in for "PRG
=".  Change the "MCU_TARGET =" line to the chip you are using.
    This Makefile currently has my latest settings in it. You should
also change the "program:" and "verify:" targets so that it uses the
chip programmer that you actually have installed.  Extra object files
you need should be listed under "OBJ =" and they will be built
automatically. Remember that all of the shell commands in the file
should start with a TAB even if the email doesn't come through that
way.
    After modifying the Makefile, just type "make" from the directory
containing your source code to compile and program the chip.
