# NOTE:
#
# This is a makefile for use while porting FreeBSD to the Alpha
# architecture. It is based on src/Makefile and is included by
# it rather than filling it with a lot of temporary crud.
#
# To use this Makefile on a NetBSD/Alpha 1.3 system, load the
# entire FreeBSD source tree, or mount /usr/src via NFS. From
# /usr/src type:
#
# make -m /usr/src/share/mk buildworld
#
# and you're away. Don't expect the build to complete. It will fail
# where the porting effort is up to. This will be somewhere in the
# build of the bootstrap libraries that are needed for the second
# set of bootstrap tools. The build will deliberately skip the
# build of libc because that involves considerable porting effort.
# The build will also create symbolic links to several of the GNU
# tools that are currently being ported/imported to FreeBSD.
#
# Warning: This build is not supposed to clobber anything on the
# =======  system you are building on, but you should consider what
# =======  you would do if that happened.
