Usage:	$(basename $0) {--version [version]} {--arch [arch]} {--with-compat32} {--build|--clean|--build-rpm [src.rpm]|--install-rpm [arch.rpm|package]|--remove-rpm [package]}
	--version:		set [version] (default: ${DEFAULT_VERSION})
	--arch:			set [arch] (default: $(uname -i))
	--with-compat32:	build with compat32 on boostrap
	--clean:		clean boostrap of [version]
	--build:		build boostrap of [version]
	--build-rpm:		build [src.rpm] on boostrap
	--install-rpm:		install [arch.rpm|package] on boostrap
	--remove-rpm:		remove [package] on boostrap

For example, 
* make a clean/plain build environment on the current archtecture:
$(basename $0) --clean --build
* build 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 compat32:
$(basename $0) --arch i386 --with-compat32 --build-rpm [src.rpm]
