+ help
+ unlzma is a compression utility using the Lempel-Ziv-Markov chain
+ compression algorithm, and range coding. Compression
+ is generally considerably better than that achieved by the bzip2
+ compressors.
+
+ The BusyBox unlzma applet is limited to de-compression only.
+ On an x86 system, this applet adds about 4K.
+
+ Unless you have a specific application which requires unlzma, you
+ should probably say N here.

+ default n
+ depends on BUSYBOX_CONFIG_UNLZMA
+ help
+ This option reduces decompression time by about 33% at the cost of
+ a 2K bigger binary.
