#ifndef CGAL_MINIBALL_CONFIGURE
#define CGAL_MINIBALL_CONFIGURE

// Remark: In case you want to fine-tune the code, feel free to change
// the options below.

// Option: Namespace name
//
// Background: By default, all data-structures and routines of the
// package are placed in a namespace called CGAL.  You can
// change this name by altering the following #define.
//
// Default value: CGAL
#define CGAL_MINIBALL_NAMESPACE CGAL

// Option: Assertions
//
// Background: The package contains lots of assertions (i.e. internal
// consistency checks).  For instance, if assertions are enabled then
// the package will complain when you add balls with negative radii.
// If you disable assertions, such tests will not be made (with the
// advantage that the code is slightly faster).  Do *not* disable
// assertions during development.
//
// Default setting: defined
#ifndef CGAL_NO_ASSERTIONS
#define CGAL_MINIBALL_DEBUG
#endif
#ifdef NDEBUG
#undef  CGAL_MINIBALL_DEBUG
#endif

// (You should not have to alter anything below here.)

// If CGAL is not being used, we need to define certain things:
#ifndef CGAL_VERSION
  namespace CGAL_MINIBALL_NAMESPACE {
    struct Tag_true {};
    struct Tag_false {};
  }
  #define CGAL_MINIBALL_NTS 
#else
  #include <CGAL/basic.h>
  #define CGAL_MINIBALL_NTS CGAL_NTS
#endif

// Define some assertion macros used in the code.
#ifdef CGAL_MINIBALL_DEBUG
  #define CGAL_MINIBALL_ASSERT(expr) assert(expr)
  #define CGAL_MINIBALL_DO_DEBUG(expr) expr
#else
  #define CGAL_MINIBALL_ASSERT(expr) ;
  #define CGAL_MINIBALL_DO_DEBUG(expr) ;
#endif

// Currently, we include all code in the header files because most
// compilers don't support exporting templates anyway:
#define CGAL_MINIBALL_NO_TEMPLATE_EXPORT

// Fixes for Metrowerks CodeWarrior 7 compilers on MacOS X:
// Unfortunately, this compiler puts the following symbols into
// the global namespace, so we put them back into std:
// (This fix is not necessary any more for CW 8 or higher.)
#if defined __MWERKS__ && defined __MACH__ && (__MWERKS__ < 0x3000)

    int rand(void) { return ::rand(); }
    double sqrt(const double x) { return ::sqrt(x); }
    double abs(const double x) { return ::abs(x); }
  }
#endif

// Fixes for GCC series 2.95.  (This fix is necessary for 2.95.2 at
// least.  But I guess it is needed for any earlier version of the 2.95
// series, too.)  Apparently, GCC doesn't come with a bitset and sstream
// implementation, that's why we include them here.

// Fixes for MIPSpro Compilers (Version 7.3.1.3m is where the problem
// occurred): The library function std::rand() is not in namespace std
// and so we put it there.  (This is only necessary when the package
// is used without CGAL; if you include any CGAL header, then CGAL will
// have fixed it already.)
