## Detailed Description

An OptionEntry defines a single option.

To have an effect, it must be added to an OptionGroup with OptionGroup::add_entry().

The long name of an option can be used to specify it in a commandline as –long_name. Every option must have a long name. To resolve conflicts if multiple option groups contain the same long name, it is also possible to specify the option as –groupname-long_name.

If an option has a short name, it can be specified as -short_name in a commandline.

The description for the option is shown in the –help output.

The arg_descripton is the placeholder to use for the extra argument parsed by the option in –help output.
