end.

调用方法：

procedure InitBugSplat();
var
  sVersion: string;
begin
  sVersion := GetFileVersion(Application.ExeName);
  if TBugSplat.Instance = nil then
    TBugSplat.Create('XXX_DSB', SDefaultProductName, sVersion);

  Application.OnException := TBugSplat.Instance.AppException;
  TBugSplat.Instance.LogPath := IncludeTrailingBackslash(g_DocumentPath) + 'Log';
  TBugSplat.Instance.EMail := 'xx@xx.com';
  TBugSplat.Instance.UserDescription := 'DSB_' + sVersion;
end;
