Usage:  $(basename $0) {--version [version]} {--arch [arch]} {--category [categories]} {--dist-upgrade} {--target [target]} {--with-compat32} {--bootstrap-dir [directory]} {--cache-dir [directory]} {--built-rpms-dir [directory]} {clean|build|build-rpm [src.rpm]|install-rpm [arch.rpm|package]|remove-rpm [package]|show-info}

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
        --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]
