19.23. Краткие аргументы #
Для удобства с некоторыми параметрами сопоставлены однобуквенные аргументы командной строки. Все они описаны в Таблице 19.5. Некоторые из этих сопоставлений существуют по историческим причинам, так что наличие однобуквенного синонима не обязательно является признаком того, что этот аргумент часто используется.

19.23. Short Options #
For convenience there are also single letter command-line option switches available for some parameters. They are described in Table 19.5. 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.
