  libgig actually consists of three parts:

  - RIFF classes (RIFF.h, RIFF.cpp): Provides convenient methods to parse and
                                     access arbitrary RIFF files.
  - DLS classes (DLS.h, DLS.cpp):    They're using the RIFF classes to parse
                                     DLS (Downloadable Sounds) Level 1 and 2
                                     files and provide abstract access to the
                                     data.
  - gig classes (gig.h, gig.cpp):    These are based on the DLS classes and
                                     provide the necessary extensions for
                                     the Gigasampler file format.

  Beside the actual library there are four example applications:

    gigdump:     Demo app that prints out the content of a .gig file.
    gigextract:  Extracts samples from a .gig file.
    dlsdump:     Demo app that prints out the content of a DLS file.
    rifftree:    Tool that prints out the RIFF tree of an arbitrary RIFF
                 file.

Requirements
============

  POSIX systems (e.g. Linux, OS X):
  ---------------------------------

  You need at least to have libtool installed to be able to build the
  library with "./configure && make".

  Additionally you need to have either libaudiofile (>= 0.2.3) or
  libsndfile (>= 1.0.2) installed which is mandatory to be able to compile
  the 'gigextract' example application. But of course 'gigextract' is still
  just an example application, so it would make sense to compile it only if
  one of those libraries are available. That would remove that hard
  dependency to those two libs. But that's not a priority for me now.
  Note: for Windows systems only libsndfile is available.

  If you want to regenerate all autotools build files (that is configure,
  Makefile.in, etc.) then you need to have automake (>= 1.5) and autoconf
  installed.  

  Non-POSIX systems (e.g. Windows):
  ---------------------------------
  
  If you don't have a POSIX system, you have to set 'POSIX' to '0' in RIFF.h.
  Instead of using POSIX calls then standard C calls will be used for file
  access. This applies e.g. to Windows systems. I would appreciate if
  somebody sends me his MS Visual Studio / .NET, Borland C++ Builder or
  Apple XCode project file! This might help others to conveniently compile
  libgig on those platforms as well.

Compiling
=========

  You can either compile the sources and install the library directly on
  your system or you can create Redhat or Debian packages.

  a) Compiling and installing directly

  Call './configure && make' on the console to compile the library, all
  tools and demo applications, documentation and install them with
  'make install'. The latter has to be called as root.

  If you are compiling from CVS you have to call 'make -f Makefile.cvs'
  to generate all autotools build files before calling
  './configure && make'.

  You can use 'make distclean' and probably 'make -f Makefile.cvs clean'
  to clean up everything again. The latter will also delete all automatic
  generated autools build files.

  b) Creating Debian packages

  Use 'dpkg-buildpackage -rfakeroot -b' to compile and create the Debian
  packages. This will generate 3 Debian packages:

    libgig:      Contains the shared library files.
    libgig-dev:  Contains the header files and documentation for building
                 applications using libgig.
    gigtools:    Contains the tools and demo applications.

  You can use 'fakeroot debian/rules clean' to clean up everything again.

  c) Creating Redhat packages

  You need to have the rpmbuild tool installed and properly configured to
  create RPM packages. To create the RPM packages do the following:

    * Get .spec file generated by ./configure and edit it as appropriate.

    * Copy the source tarball to "/usr/src/<rpmdir>/SOURCES" directory,
      where <rpmdir> is dependent to the system you are using. For SuSE
      <rmpdir> will be "packages", for Mandrake <rpmdir> is "RPM" and for
      Redhat / Fedora <rpmdir> always equals "redhat".

    * Build the rpm(s) by invoking 'rpmbuild -bb <specfile>' from the
      command line.

  On success, the resulting rpm(s) can usually be found under the proper
  "/usr/src/<rpmdir>/RPMS/<arch>" directory.

API Documentation
=================

 If you have Doxygen installed you can generate the API documentation by
 running 'make docs' in the sources' top level directory. The API
 documentation will be generated in the 'doc' subdirectory.

Patches
=======
  If you find bugs or have improvements, your patches are always welcome!
  Send them either directly to me or to the LinuxSampler developer's mailing
  list <linuxsampler-devel@lists.sourceforge.net>.

Credits
=======
  The initial library was based on the reverse engineering effort of
  Paul Kellett and Ruben van Royen. We owe current support for the quite new
  Gigasampler v3 format to Andreas Persson. Please also have a look at the
  ChangeLog for all those who contributed. Thanks for your great work!
