+	default BUSYBOX_DEFAULT_AR  # needs to be improved to be able to replace binutils ar
+	help
+	  ar is an archival utility program used to create, modify, and
+	  extract contents from archives. An archive is a single file holding
+	  a collection of other files in a structure that makes it possible to
+	  retrieve the original individual files (called archive members).
+	  The original files' contents, mode (permissions), timestamp, owner,
+	  and group are preserved in the archive, and can be restored on
+	  extraction.
+
+	  The stored filename is limited to 15 characters. (for more information
+	  see long filename support).
+	  ar has 60 bytes of overheads for every stored file.
+
+	  This implementation of ar can extract archives, it cannot create or
+	  modify them.
+	  On an x86 system, the ar applet adds about 1K.
+
+	  Unless you have a specific application which requires ar, you should
+	  probably say N here.

+	help
+	  By default the ar format can only store the first 15 characters
+	  of the filename, this option removes that limitation.

+	help
+	  bunzip2 is a compression utility using the Burrows-Wheeler block

+	  is generally considerably better than that achieved by more

+	  performance of the PPM family of statistical compressors.

+	  This reduces dpkg-deb to the equivalent of
