#
# Filename:     Makefile
#
# Project:      Zip CPU -- a small, lightweight, RISC CPU soft core
#
# Purpose:      This makefile attempts to build the ZipCPU toolchain.  This 
#               includes binutils and GCC.  (Eventually, it will include the
#       standard library as well ...)  Configuration options for binutils, GCC,
#       and newlib can be found (and set) in the gas-script.sh, gcc-script.sh,
#       and nlib-script.sh files respectively.
#
# Targets:
#
#       make all:
#               Includes the install target, but also the pdf documentation
#               files that come with binutils and gcc.  Building this target
#               will require a LaTeX distribution in addition to the needs of
#               the other targets.  Since the PDFs can be found on line,
#               building them is not really necessary, but may be quite useful.
#
#       make install
#               Attempts to build binutils, gcc, and newlib, and to install 
#               them into the local install directory.
#
#               This is the default target
#
#       make binutils
#       make gcc
#       make newlib
#               Builds the respective packages
#
#       make binutils-install
#       make gcc-install
#       make newlib-install
#               Installs the respective packages into the install directory,
#               building them first if necessary.
#
#       make clean
#               Removes all build products--to include the source directories
#               that are built from patched tarballs.
