separator file的用法和樣例：
例句
- The stylesheet attempts to guess the file separator for your system by querying.
和其他屬性試圖猜測系統所用的文件分隔符。 - This prevents any missing file errors you might get as a result of using the wrong delimiter, and it makes your code more portable.
這樣可以防止由于使用分隔符而導致文件丟失錯誤，同時(shí)這樣還可以讓你的代碼更輕便。
