我见过的每一个软件都包含一个文件开头的版权声明，并且需要大量的评论。因此，您必须向下滚动才能看到代码，这有点烦人，特别是当代码本身非常短时。
我认为将版权声明保留在文件底部并将所有子句合并为单行（或少数行）会更好。这只是为了满足正式问题。 LICENSE文件中提供了易于阅读的版本。
但到目前为止我还没有见过这种做法。这只是一种部落习俗还是有原因的呢？

虽然它不一定是定制或要求，但标准倾向于规定评论应该进行任何代码定义。以NDOC notation为例。
在版权的情况下，您通常希望人们在继续使用您的代码之前阅读它（EULA始终显示在安装程序的开头）。如果版权声明放在代码定义的底部，则很有可能会被忽略。

如果您将版权注释放在文件的开头，则当有人打开文件时，版权声明是可见的（如果打开文件的人不使用自动转到上次访问行的编辑器）。如果版权评论放在文件的底部，人们需要滚动到最后才能看到版权，这是有人应该有兴趣看的第一件事。
