  \class QmXmpPlayer qmxmpplayer.h
  \brief Provides functionality for playing tracker modules.

  This class is a wrapper around XMP (Extended Module Player) which makes it
  possible to play tracker modules. XMP 2.0.4 can play 48 formats:

  XM (Fast Tracker II), MOD (Noise/Fast/Protracker), MOD (Startrekker/Audio Sculpure),
  M15 (Soundtracker), IT (Impulse Tracker), S3M (Scream Tracker 3),
  STM (Scream Tracker 2), STX (STMIK 0.2), MTM (Multitracker), MTN (Soundtracker 2.6/Ice Tracker),
  IMF (Imago Orpheus), PTM (Protracker), MDL (Digitrakker), ULT (Ultra Tracker),
  MED (MED/OctaMED), PTM (Poly Tracker), DIGI (DIGI Booster), EMOD (Quadra Composer),
  OKT (Oktalyzer), SFX (SoundFX 1.3), FAR (Farandole Composer), STIM (Slamtilt),
  FC-M (FC-M Packer), KSM (Kefrens Sound Machine), WN (Wanton Packer), PM (Power Music),
  KRIS (ChipTracker), UNIC (Unic Tracker), PRU1 (ProRunner 1.0), PRU2 (ProRunner 2.0),
  PM01 (Promizer 0.1), PM10 (Promizer 1.0c), PM18 (Promizer 1.8a), PM20 (Promizer 2.0),
  PM40 (Promizer 4.0), AC1D (AC1D Packer), PP10 (Pha Packer), XANN (XANN Packer),
  ZEN (Zen Packer), NP (NoisePacker), DI (Digital Illusions), MP (Module Protector),
  669 (Composer 669), FNK (Funktracker), AMD (Amusic Adlib Tracker),
  RAD (Reality Adlib Tracker), CRB (Heatseeker), ALM (Aley Keptr)  

  This code is based on the simple.c example that comes with the library.
