/** Describes positional options.

|
|
The class allows to guess option names for positional options, which
|
|
are specified on the command line and are identified by the position.
|
|
The class uses the information provided by the user to associate a name
|
|
with every positional option, or tell that no name is known.
|
|
|
|
The primary assumption is that only the relative order of the
|
|
positional options themselves matters, and that any interleaving
|
|
ordinary options don't affect interpretation of positional options.
|
|
|
|
The user initializes the class by specifying that first N positional
|
|
options should be given the name X1, following M options should be given
|
|
the name X2 and so on.
