- This class allows you to treat debugging output in a similar
- (stream-based) fashion on different platforms. Under
- Windows, an ostream constructed with this buffer outputs
- to the debugger, or other program that intercepts debugging
- output. On other platforms, the output goes to standard error (cerr).
-
- This is soon to be obsolete, replaced by wxLog functionality.
