3# Makefile for building PICOBSD kernels and running crunchgen
4#
5# Needs SRC pointing to the source tree,
6# MY_TREE ponting to my tree
7# BUILDDIR pointing to the build directory
8# PICO_OBJ pointing to the object directory
9# When building a kernel, also need ${name} from the environment
10# and CONFIG may indicate an alternate config program
11

13CONFIG?=config

15# These 3 variables determine where the kernel is built.
16# If config were smart enough, we could place the config
17# file in some other place than ${SRC}/sys/i386/conf, but
18# at the moment (Oct.2001) this is not possible yet.
