为什么需要修改 LICENSE，是因为学校方面有要求吗？

[YDX-2147483647]

@spencerwooo 学校没有要求，主要是考虑实用。

现在许可证注释太长（有些文件中许可证比有用内容还长），不时有同学把注释一股脑全删掉，导致% ! TeX program = xelatex、盲审设置方法这种有用注释也丢了，造成无法编译或重复提问。因此这个PR删除了模板包templates/**/*.{tex,bib}中的许可证注释。（bithesis.dtx等仍然采用 LPPL，没有改。）

另外我个人认为，templates/**/*.{tex,bib}中几乎没有实质性内容，不足以声明著作权。

后来考虑把这块改掉是觉得模板部分是要分发给最终用户，最终用户用它来写论文，那么这个东西好像不保留版权更合理一些，这样用户可以自由的使用这个模板，不受LPPL中条款的限制。目前不涉及学校的要求。修改仅限分发给用户的模板，而非项目本体。

是否需要补充类似于“没有任何形式的担保”之类的语句呢，也请大家考虑看看

我也认同在模板文件中删掉许可声明。

LPPL 许可明确了这部分：

anyone as a result of any failure of the Work to operate with any other
programs), even if the Copyright Holder or said author or said other
party has been advised of the possibility of such damages.

整体项目保留使用 LPPL 许可能覆盖。
