- * liblzma is a LZMA compression library with a zlib-like API.

+ * liblzma is a public domain general-purpose data compression library with
+ * a zlib-like API. The native file format is .xz, but also the old .lzma
+ * format and raw (no headers) streams are supported. Multiple compression
+ * algorithms (filters) are supported. Currently LZMA2 is the primary filter.
