//config: depends on BBCONFIG
//config: help
//config: Store bbconfig data in compressed form, uncompress them on-the-fly
//config: before output.
//config: If you have a really tiny busybox with few applets enabled (and
//config: bunzip2 isn't one of them), the overhead of the decompressor might
//config: be noticeable. Also, if you run executables directly from ROM
//config: and have very little memory, this might not be a win. Otherwise,
//config: you probably want this.
