# NAME:
# boot-strap
#
# SYNOPSIS:
# boot-strap [--"configure_arg" ... ][-s "srcdir"][-m "mksrc"]\\
# ["prefix" ["bmakesrc" ["mksrc"]]]
#
# DESCRIPTION:
# This script is used to configure/build bmake it builds for
# each OS in a subdir to keep the src clean.
# On successful completion it echos commands to put the new
# bmake binary into the /configs tree (if it exists)
# (http://www.crufty.net/FreeWare/configs.html), $prefix/bin
# and a suitable ~/*bin directory.
#
# Options:
#
# -c "rc"
# Pick up settings from "rc".
# We look for '.bmake-boot-strap.rc' before processing
# options.
#
# --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 $prefix/share.
#
# --mksrc "mksrc"
# Indicate where the mk files can be found.
# Default is ./mk or ../mk, set to 'none' to force
# building without "mksrc" but in that case a sys.mk
# needs to exist in the default syspath ($share_dir/mk)
#
# 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="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-default-sys-path="syspath"
# set an explicit default "syspath" which is where bmake
# will look for sys.mk and friends.
