### Configuring parser
Parsers have several fields affecting their behaviour. For example, `description` field sets the text to be displayed in the help message between the usage message and the listings of options and arguments. Another is `name`, which overwrites the name of the program which is used in the usage message(default value is inferred from command line arguments).

There are several ways to set fields. The first is to call a parser with a table containing some fields.

### Adding options
Options can be added using `:option()` method. It returns an Option instance, which can be configured in the same way as Parsers. The `name` field is required. An option can have several aliases, which can be set using `aliases` field or by continuesly calling the Option instance.

Note that the data passed to `optional` option is stored in an array. That is necessary to distiguish whether the option was invoked without an argument or it was not invoked at all.

#### Setting number of invocations
For options, it is possible to control how many times they can be used. argparse uses `count` field to set how many times an option can be invoced. The value of the field is interpreted in the same way `args` is.
