-/**

- * Inputs may come from Files, Strings or other sources. The
- * preprocessor maintains a stack of Sources. Operations such as
- * file inclusion or token pasting will push a new source onto
- * the Preprocessor stack. Sources pop from the stack when they
- * are exhausted; this may be transparent or explicit.
- *
- * BUG: Error messages are not handled properly.
