Options:
	--version:		set [version] (default: ${DEFAULT_VERSION})
	--arch:			set [arch] (default: $(uname -i))
	--category:		set [categories] (default: ${CATEGORIES})
	--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
	--rpmbuild-define:	give a option --define [macro_expr] to rpmbuild
	--rpmbuild-with:	give a option --with [bcond_with] to rpmbuild
	--rpmbuild-without:	give a option --without [bcond_with] to rpmbuild
	--sign:			sign built rpms
	--no-install:		build only a source rpm - do NOT install a built rpm
	--bootstrap-dir:	set a bootstrap directory (default: ${VBOOTSTRAP_DIR})
	--cache-dir:		set a directory to cache rpms (default: ${CACHE_DIR})
	--built-rpms-dir:	set a directory to store built rpms in chroot (default: ${BUILT_RPMS_DIR})

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
	show-info:		show basic informations and logs in chroot

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]
