- * Quick fixes to fix the broken tree. Needed for my morning compiles.

- * Here is the simple debug parser and the debug2html converter. Still to do:
- *
- * * Debug message filtering.

- * (If it looks at all strange I'll ask for help.)

- * Parse input one character at a time.
- *
- * Input: state - A pointer to a token variable. This is used to
- * maintain the parser state between calls. For
- * each input stream, you should set up a separate
- * state variable and initialize it to dbg_null.
- * Pass a pointer to it into this function with each
- * character in the input stream. See dbg_test()
- * for an example.
- * c - The "current" character in the input stream.
- *
- * Output: A token.
- * The token value will change when delimiters are found,
- * which indicate a transition between syntactical objects.
- * Possible return values are:
- *
- * dbg_null - The input character was an end-of-line.
- * This resets the parser to its initial state
- * in preparation for parsing the next line.
- * dbg_eof - Same as dbg_null, except that the character
- * was an end-of-file.
- * dbg_ignore - Returned for whitespace and delimiters.
- * These lexical tokens are only of interest
- * to the parser.
- * dbg_header - Indicates the start of a header line. The
- * input character was '[' and was the first on
- * the line.
- * dbg_timestamp - Indicates that the input character was part
- * of a header timestamp.
- * dbg_level - Indicates that the input character was part
- * of the debug-level value in the header.
- * dbg_sourcefile - Indicates that the input character was part
- * of the sourcefile name in the header.
- * dbg_function - Indicates that the input character was part
- * of the function name in the header.
- * dbg_lineno - Indicates that the input character was part
- * of the DEBUG call line number in the header.
