# NAME:
# boot-strap
#
# SYNOPSIS:
# boot-strap ["options"]
# boot-strap --prefix=/opt --install
# boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION
# boot-strap ["options"] op=build
# boot-strap ["options"] op=install
#
# DESCRIPTION:
# This script is used to configure/build bmake it builds for
# each host-target in a different subdir to keep the src clean.
# There is no requirement for an existing make(1).
#
# On successful completion if no '--install' flag is given,
# it echos a command to do installation.
#
# The variable "op" defaults to 'all', and is affected by
# '--install' flag as above.
# Other values include:
#
# configure
# Just run 'configure'
#
# build
# If 'configure' has not been done, do it, then
# run the build script, and finally 'test'.
#
# install
# If 'build' has not been done, do it, 'test' then
# install.
#
# clean
# attempt to clean up
#
# test
# run the unit-tests. Done automatically after 'build'
# and before 'install'.
#
# The above are leveraged by a trivial makefile for the benefit
# of those that have './configure; make; make install' baked
# into them.
#
# Options:
#
# -c "rc"
# Pick up settings from "rc".
# We look for '.bmake-boot-strap.rc' before processing
# options (unless SKIP_RC is set in environment).
#
# --share "share_dir"
# Where to put man pages and mk files.
# If $prefix ends in $HOST_TARGET, and $prefix/../share
# exits, the default will be that rather than $prefix/share.
#
# --mksrc "mksrc"
# Indicate where the mk files can be found.
# Default is $Mydir/mk
#
# --install
# If build and test work, run bmake install.
# BINDIR=$prefix/bin
# SHAREDIR=$prefix/share
#
# --install-host-target
# As for '--install' but BINDIR=$prefix/$HOST_TARGET/bin
# This is useful when $prefix/ is shared by multiple
# machines.
#
# Flags relevant when installing:
#
# -DWITHOUT_INSTALL_MK
# Skip installing mk files.
# By default they will be installed to $prefix/share/mk
#
# -DWITH_PROG_VERSION
# Install 'bmake' as 'bmake-$MAKE_VERSION'
# A symlink will be made as 'bmake' unless
# -DWITHOUT_PROG_LINK is set.
#
# Possibly useful configure_args:
#
# --without-meta
# disable use of meta mode.
#
# --without-filemon
# disable use of filemon(9) which is currently only
# available for NetBSD and FreeBSD.
#
# --with-filemon=ktrace
# on NetBSD or others with fktrace(2), use ktrace
# version of filemon.
#
# --with-filemon="path/to/filemon.h"
# enables use of filemon(9) by meta mode.
#
# --with-machine="machine"
# set "machine" to override that determined by
# machine.sh
#
# --with-force-machine="machine"
# force "machine" even if uname(3) provides a value.
#
# --with-machine_arch="machine_arch"
# set "machine_arch" to override that determined by
# machine.sh
#
# --with-force_machine_arch="machine_arch"
# force "machine_arch" to override that determined by
# machine.sh
#
# --with-default-sys-path="syspath"
# set an explicit default "syspath" which is where bmake
# will look for sys.mk and friends.

You can install by running:
$0 $cmd_args op=install
Use --install-prefix=/something to install somewhere other than $prefix
Use --install-destdir=/somewhere to set DESTDIR during install
Use --install-host-target to use INSTALL_BIN=$HOST_TARGET/bin
Use -DWITH_PROG_VERSION to install as bmake-$MAKE_VERSION
Use -DWITHOUT_PROG_LINK to suppress bmake -> bmake-$MAKE_VERSION symlink
Use -DWITHOUT_INSTALL_MK to skip installing files to $prefix/share/mk
