80/*
81 * `type`::
82 * holds the type of the option, you must have an OPTION_END last in your
83 * array.
84 *
85 * `short_name`::
86 * the character to use as a short option name, '\0' if none.
87 *
88 * `long_name`::
89 * the long option (without the leading dashes) or subcommand name,
90 * NULL if none.
91 *
92 * `value`::
93 * stores pointers to the values to be filled.
94 *
95 * `precision`::
96 * precision of the integer pointed to by `value` in number of bytes. Should
97 * typically be its `sizeof()`.
98 *
99 * `argh`::
100 * token to explain the kind of argument this option wants. Does not
101 * begin in capital letter, and does not end with a full stop.
102 * Should be wrapped by N_() for translation.
103 * Is automatically enclosed in brackets when printed, unless it
104 * contains any of the following characters: ()<>[]|
105 * E.g. "name" is shown as "<name>" to indicate that a name value
106 * needs to be supplied, not the literal string "name", but
107 * "<start>,<end>" and "(this|that)" are printed verbatim.
108 *
109 * `help`::
110 * the short help associated to what the option does.
111 * Must never be NULL (except for OPTION_END and OPTION_SUBCOMMAND).
112 * OPTION_GROUP uses this pointer to store the group header.
113 * Should be wrapped by N_() for translation.
114 *
115 * `flags`::
116 * mask of parse_opt_option_flags.
117 * PARSE_OPT_OPTARG: says that the argument is optional (not for BOOLEANs)
118 * PARSE_OPT_NOARG: says that this option does not take an argument
119 * PARSE_OPT_NONEG: says that this option cannot be negated
120 * PARSE_OPT_HIDDEN: this option is skipped in the default usage, and
121 * shown only in the full usage.
122 * PARSE_OPT_LASTARG_DEFAULT: says that this option will take the default
123 * value if no argument is given when the option
124 * is last on the command line. If the option is
125 * not last it will require an argument.
126 * Should not be used with PARSE_OPT_OPTARG.
127 * PARSE_OPT_NODASH: this option doesn't start with a dash; can only be a
128 * short option and can't accept arguments.
129 * PARSE_OPT_LITERAL_ARGHELP: says that argh shouldn't be enclosed in brackets
130 * (i.e. '<argh>') in the help message.
131 * Useful for options with multiple parameters.
132 * PARSE_OPT_NOCOMPLETE: by default all visible options are completable
133 * by git-completion.bash. This option suppresses that.
134 * PARSE_OPT_COMP_ARG: this option forces to git-completion.bash to
135 * complete an option as --name= not --name even if
136 * the option takes optional argument.
137 *
138 * `callback`::
139 * pointer to the callback to use for OPTION_CALLBACK
140 *
141 * `defval`::
142 * default value to fill (*->value) with for PARSE_OPT_OPTARG.
143 * OPTION_{BIT,SET_INT} store the {mask,integer} to put in the value when met.
144 * CALLBACKS can use it like they want.
145 *
146 * `ll_callback`::
147 * pointer to the callback to use for OPTION_LOWLEVEL_CALLBACK
148 *
149 * `subcommand_fn`::
150 * pointer to a function to use for OPTION_SUBCOMMAND.
151 * It will be put in value when the subcommand is given on the command line.
