Javadoc documentation显示以下内容，作为如何使用{@docRoot}在每个Javadoc生成的页面上显示copyright.html文件内容的示例。
Voting Table
id = 1, citizen_id = 1, candidate_name = "Bern Nie"
id = 2, citizen_id = 2, candidate_name = "Bern Nie"
id = 3, citizen_id = 3, candidate_name = "Hill Arry"
id = 4, citizen_id = 3, candidate_name = "Hill Arry"
id = 5, citizen_id = 3, candidate_name = "Hill Arry"
我的问题是：如何在{@docRoot}中创建 copyright.html 文件？
谢谢， 百里
