	// Parameters:
	//   msg:
	//      message to display.  Likely to be the output of stack trace
	//      with other information such as version number, etc.
	//   emailButtonFuncPtr:
	//      Pointer to func to call when the email button is pressed.
	//      Passes a pointer to the complete assert string.
	//   titleText:
	//      Message to display in on title bar of assert box.  If NULL, prints "Assertion Failed".
	//      Isolated so that it may be translated easily.
	//   okButtonText:
	//      Message to display in "OK" button.  If NULL, prints "OK".
	//      Isolated so that it may be translated easily.

	//      Isolated so that it may be translated easily.
	//   editAreaText:

	//       "Please enter description of what you were
	//       doing at the time this assertion occured here."
	//   parentBox:
	//      What the parent of this box is.  If null, it is a top level wnd
	//      Note, thus "void *" is really an HWND.  I do not declare it as such
	//      to avoid extraneous inclusion of windows.h
	// Return:
	//   Returns an HWND to this box.  Should be passed to runAssertBox.
	//   These two calls are seperated from one another so that the 
	//   caller may center the assert box or perform other deisred manipulations
	//   before it is shown.

// Assert.h is defined to call the following function

// to do the tings you want.  See the LEVEL 2 template code
// in zassert_template.cpp

// This code is somewhat complicated by the portability issues.
// WIN32 and POSIX (not surprisingly) seem to difer on the 
// function declarations for the call from the assert macro.
// So, the ASSERTFUNC macro defines function in a portable way

// The assert in assert.h is wrapped in a #ifndef _DEBUG
// block which means that they will not assert in non-debug 
// builds.  Unfortunatly, this is not always the desired behavior.
// Thus, the following macro "aasert" is NOT in such a wrapper and will
// thus *always* assert in any build.
