- * Kaitai Stream class (kaitai::kstream) is an implementation of

- * for C++/STL. It's implemented as a wrapper over generic STL std::istream.
- *
- * It provides a wide variety of simple methods to read (parse) binary
- * representations of primitive types, such as integer and floating
- * point numbers, byte arrays and strings, and also provides stream
- * positioning / navigation methods with unified cross-language and
- * cross-toolkit semantics.
- *
- * Typically, end users won't access Kaitai Stream class manually, but would
- * describe a binary structure format using .ksy language and then would use
- * Kaitai Struct compiler to generate source code in desired target language.
- * That code, in turn, would use this class and API to do the actual parsing
- * job.
