20.18. Short Options #

为了方便起见，对于某些参数还提供了单字母命令行选项开关。它们在 Table 20.4中进行了说明。其中一些选项出于历史原因而存在，其作为单字母选项的存在并不一定表示认可大量使用该选项。

For convenience there are also single letter command-line option switches available for some parameters. They are described in Table 20.4. Some of these options exist for historical reasons, and their presence as a single-letter option does not necessarily indicate an endorsement to use the option heavily.
