576 release Run "make release" (includes kernels & distrib media).
578 Other operations:
579 help Show this message and exit.
580 makewrapper Create ${toolprefix}make-\${MACHINE} wrapper and ${toolprefix}make.
581 Always performed.
582 cleandir Run "make cleandir". [Default unless -u is used]
583 obj Run "make obj". [Default unless -o is used]
584 tools Build and install tools.
585 install=idir Run "make installworld" to \`idir' to install all sets
586 except \`etc'. Useful after "distribution" or "release"
587 kernel=conf Build kernel with config file \`conf'
588 releasekernel=conf Install kernel built by kernel=conf to RELEASEDIR.
589 modules Build kernel modules.
590 rumptest Do a linktest for rump (for developers).
591 sets Create binary sets in
592 RELEASEDIR/RELEASEMACHINEDIR/binary/sets.
593 DESTDIR should be populated beforehand.
594 sourcesets Create source sets in RELEASEDIR/source/sets.
595 syspkgs Create syspkgs in

597 iso-image Create CD-ROM image in RELEASEDIR/iso.
598 iso-image-source Create CD-ROM image with source in RELEASEDIR/iso.
599 params Display various make(1) parameters.
601 Options:
602 -a arch Set MACHINE_ARCH to arch. [Default: deduced from MACHINE]
603 -B buildId Set BUILDID to buildId.
604 -C cdextras Append cdextras to CDEXTRA variable for inclusion on CD-ROM.
605 -D dest Set DESTDIR to dest. [Default: destdir.MACHINE]
606 -E Set "expert" mode; disables various safety checks.
607 Should not be used without expert knowledge of the build system.
608 -h Print this help message.
609 -j njob Run up to njob jobs in parallel; see make(1) -j.
610 -M obj Set obj root directory to obj; sets MAKEOBJDIRPREFIX.
611 Unsets MAKEOBJDIR.
612 -m mach Set MACHINE to mach; not required if NetBSD native.
613 -N noisy Set the noisyness (MAKEVERBOSE) level of the build:
614 0 Minimal output ("quiet")
615 1 Describe what is occurring
616 2 Describe what is occurring and echo the actual command
617 3 Ignore the effect of the "@" prefix in make commands
618 4 Trace shell commands using the shell's -x flag
619 [Default: 2]
620 -n Show commands that would be executed, but do not execute them.
621 -O obj Set obj root directory to obj; sets a MAKEOBJDIR pattern.
622 Unsets MAKEOBJDIRPREFIX.
623 -o Set MKOBJDIRS=no; do not create objdirs at start of build.
624 -R release Set RELEASEDIR to release. [Default: releasedir]
625 -r Remove contents of TOOLDIR and DESTDIR before building.
626 -S seed Set BUILDSEED to seed. [Default: NetBSD-majorversion]
627 -T tools Set TOOLDIR to tools. If unset, and TOOLDIR is not set in

630 install from an UNPRIVED build with proper file permissions.
631 -u Set MKUPDATE=yes; do not run "make cleandir" first.
632 Without this, everything is rebuilt, including the tools.
633 -V v=[val] Set variable \`v' to \`val'.
634 -w wrapper Create ${toolprefix}make script as wrapper.
635 [Default: \${TOOLDIR}/bin/${toolprefix}make-\${MACHINE}]
