- * SBjsiString, string class that is a subset of STL wstring
- *
- * The SBjsiString class stores a string in a grow-only buffer, a
- * functional subset of the STL wstring class. This header merely
- * exists to make it easy to eliminate the use of STL wstring which
- * does not exist on some Linux versions.
