  -    longDescription = ''
  -      Libsndfile is a C library for reading and writing files containing
  -      sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format)
  -      through one standard library interface.  It is released in source
  -      code format under the GNU Lesser General Public License.
  -
  -      The library was written to compile and run on a Linux system but
  -      should compile and run on just about any Unix (including MacOS X).
  -      There are also pre-compiled binaries available for 32 and 64 bit
  -      windows.
  -
  -      It was designed to handle both little-endian (such as WAV) and
  -      big-endian (such as AIFF) data, and to compile and run correctly on
  -      little-endian (such as Intel and DEC/Compaq Alpha) processor systems
  -      as well as big-endian processor systems such as Motorola 68k, Power
  -      PC, MIPS and SPARC.  Hopefully the design of the library will also
  -      make it easy to extend for reading and writing new sound file
  -      formats.
