##  Ask Kresten if you have any troubles / questions.

#
# ** MANUAL BUILDS **
#
# Use: 
#	setenv RC_ARCHS='i386 m68k ...'
#	setenv RC_CFLAGS='-arch i386 -arch m68k ...'
#	make debug TARGETS='i386 m68k ...' HOSTS='i386 ...'
#
# from this directory to do manual builds.  The build compiler(s) will
# appear in ./obj/cc-<target>-on-<host>/ subdirectories of here.  Use
# "./xgcc -B./" in there to run the specific compiler.  You can also
# just cd to a specific ./obj subdirectory and type "make <foo>" to build
# a specific program, like "cpp" or "cc1objplus".  
#
# The makefile will automatically make a clone of the latest binaries
# the first time "make debug" is run.  The binaries are kept outside
# of the revision control system.

#
# ** AUTOMATIC BUILDS **
#
# Automatic builds strictly follow the RC makefile API standards.  However,
# in order to do a full build, a bootstrap is needed.  To do this, simply
# do "make bootstrap" on the build machine, and install the resulting
# symbols in the BuildRoot.  Then, do an ordinary "make install". 
#

# Enable NeXT extensions to (gnu)make.
