  * \brief       The public API of liblzma data compression library
  *
  * 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.
  *
  * liblzma is part of XZ Utils <http://tukaani.org/xz/>. XZ Utils includes

  * exists and that it typedefs at least uint8_t, uint32_t, and uint64_t,
  * and that, in case of incomplete inttypes.h, unsigned int is 32-bit.
  * If the application already takes care of setting up all the types and
  * macros properly (for example by using gnulib's stdint.h or inttypes.h),
  * we try to detect that the macros are already defined and don't include
  * inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to
  * force this file to never include any system headers.

  * Some could argue that liblzma API should provide all the required types,
  * for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was
- * seen unnecessary mess, since most systems already provide all the necessary

  * Note that liblzma API still has lzma_bool, because using stdbool.h would

  * necessarily the same as sizeof(bool) in C++.
