	help
	ar is an archival utility program used to create, modify, and
	extract contents from archives. In practice, it is used exclusively
	for object module archives used by compilers.

	Unless you have a specific application which requires ar, you should
	probably say N here: most compilers come with their own ar utility.

	bool "Support long filenames (not needed for debs)"
	default BUSYBOX_DEFAULT_FEATURE_AR_LONG_FILENAMES
	depends on BUSYBOX_CONFIG_AR
	help
	By default the ar format can only store the first 15 characters

	bunzip2 is a compression utility using the Burrows-Wheeler block
	sorting text compression algorithm, and Huffman coding. Compression
	is generally considerably better than that achieved by more
	conventional LZ77/LZ78-based compressors, and approaches the
	performance of the PPM family of statistical compressors.

	Unless you have a specific application which requires bunzip2, you

	help
	cpio is an archival utility program used to create, modify, and
	extract contents from archives.
	cpio has 110 bytes of overheads for every stored file.

	This implementation of cpio can extract cpio archives created in the
