-// This class manages a fixed-size, null-terminated string buffer. It is meant
-// to be allocated on the stack, and it makes no use of the heap internally. In
-// most cases you'll just want to use a std::(w)string, but when you need to
-// avoid the heap, you can use this class instead.
-//
-// Methods are provided to read the null-terminated buffer and to append data
-// to the buffer, and once the buffer fills-up, it simply discards any extra
-// append calls.
-//
-// Since this object clips if the internal fixed buffer is exceeded, it is
-// appropriate for exception handlers where the heap may be corrupted. Fixed
-// buffers that overflow onto the heap are provided by Stack[W]String.
-// (see stack_container.h).
