The use of aliases is my preferred method for using namespaces for two reasons: First, if I later rename the namespace, I only have one line of code to change per source file.
由于两个原因，我喜欢对名称空间使用别名：首先，如果以后要改变名称空间，在每个源代码文件中只有一行需要修改。
By the way, that's a comment on the first line (with the name of the source file for the code example).
顺便说一下，在第一行有一句注释(在代码例子中是源文件的名字)。
The best source of ideas and code comes from experienced practitioners of the command line.
最有效的得到思想和代码的途径就是咨询那些在命令行方面具有丰富经验的行家。
