# The user-driven targets are:
#
# universe - *Really* build *everything* (buildworld and
# all kernels on all architectures).
# buildworld - Rebuild *everything*, including glue to help do
# upgrades.
# installworld - Install everything built by "buildworld".
# world - buildworld + installworld.
# buildkernel - Rebuild the kernel and the kernel-modules.
# installkernel - Install the kernel and the kernel-modules.
# installkernel.debug
# reinstallkernel - Reinstall the kernel and the kernel-modules.
# reinstallkernel.debug
# kernel - buildkernel + installkernel.
# update - Convenient way to update your source tree (cvs).
# check-old - Print a list of old files/directories in the system.
# delete-old - Delete obsolete files and directories interactively.
# delete-old-libs - Delete obsolete libraries interactively.
#
# This makefile is simple by design. The FreeBSD make automatically reads
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
# command line. By keeping this makefile simple, it doesn't matter too
# much how different the installed mk files are from those in the source
# tree. This makefile executes a child make process, forcing it to use
# the mk files from the source tree which are supposed to DTRT.
#
# The user-driven targets (as listed above) are implemented in Makefile.inc1.
#
# If you want to build your system from source be sure that /usr/obj has
# at least 400MB of diskspace available.
#
# For individuals wanting to build from the sources currently on their
# system, the simple instructions are:
#
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. `make world'
#
# For individuals wanting to upgrade their sources (even if only a
# delta of a few days):
#
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. `make buildworld'
# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
# 6. `mergemaster -p'
# 7. `make installworld'
# 8. `make delete-old'
# 9. `mergemaster'
# 10. `reboot'
# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
# cross build world for other machine types using the buildworld target,
# and once the world is built you can cross build a kernel using the
# buildkernel target.
#
# Define the user-driven targets. These are listed here in alphabetical
# order, but that's not important.
#
# Targets that begin with underscore are internal targets intended for
# developer convenience only. They are intentionally not documented and
# completely subject to change without notice.
