+ * \brief String literal wrapper
+ *
+ * The \c basic_string_literal is a thin wrapper around a constant string literal.
+ * It provides interface similar to STL strings, but because of read-only nature
+ * of string literals, lacks ability to modify string contents. However,
+ * \c basic_string_literal objects can be assigned to and cleared.
+ *
+ * The main advantage of this class comparing to other string classes is that
+ * it doesn't dynamically allocate memory and therefore is fast, thin and exception safe.
