在尝试生成Doxygen文档时，我收到了很多警告
Found unknown command `\asf_license_start'
因为我在我的项目中使用Atmel Software Framework（ASF）。因此，我的很多文件都有许可代码，如下所示。此代码包含命令\ asf_license_start和\ asf_license_stop，它们是Doxygen不知道的命令。
我试图寻找外部包，但没找到任何东西。我在Atmel工作室安装了Doxygen Integrator，并将Doxygen Path更改为我的Doxygen安装位置。
有没有人知道\ asf_license_start命令在文档中应该做什么。
我希望那里的某个人能够帮助我解决这个问题，因为它会对警告反馈进行监管，并且更难找到更重要的问题。
