Usage:	$(basename $0) {--version [version]} {--arch [arch]} {--dist-upgrade} {--target [target]} {--with-compat32} {clean|build|build-rpm [src.rpm]|install-rpm [arch.rpm|package]|remove-rpm [package]}

Options:
	--version:		set [version] (default: ${DEFAULT_VERSION})
	--arch:			set [arch] (default: $(uname -i))
	--dist-upgrade:		make VineSeed bootstrap via ${STABLE_VERSION}
	--unionfs		cover a bootstrap with unionfs
	--target:		build rpms with [target]
	--with-compat32:	build rpms with compat32 on boostrap

Actions:
	clean:			clean the boostrap of [version]
	build:			build a boostrap of [version]
	build-rpm:		build [src.rpm] on a boostrap
	install-rpm:		install [arch.rpm|package] on a boostrap
	remove-rpm:		remove [package] on a boostrap

For example, 
* make a clean/plain build environment on the current archtecture:
$(basename $0) --clean --build
* build rpms from the specified source rpm:
$(basename $0) --build-rpm [src.rpm]
* make a plain build environment for Vine Linux 4.2:
$(basename $0) --version 4.2 --clean --build
* make a i386 chroot on x86_64:
$(basename $0) --arch i386 --clean --build
* build a kernel package with target i686
$(basename $0) --target i686 --build-rpm [kernel src.rpm]
* build a compat32 package:
$(basename $0) --arch i386 --with-compat32 --build-rpm [src.rpm]
