-// Package frostfsapiclient provides functionality for IR application communication with FrostFS network.
-//
-// The basic client for accessing remote nodes via FrostFS API is a FrostFS SDK Go API client.
-// However, although it encapsulates a useful piece of business logic (e.g. the signature mechanism),
-// the IR application does not fully use the client's flexible interface.
-//
-// In this regard, this package represents an abstraction -- a type-wrapper over the base client.
-// The type provides the minimum interface necessary for the application and also allows you to concentrate
-// the entire spectrum of the client's use in one place (this will be convenient both when updating the base client
-// and for evaluating the UX of SDK library). So, it is expected that all application packages will be limited
