+ * 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.
+ * dbg_message - Indicates that the input character was part

- * I've moved the debugparse module files into the ubiqx directory because I
- * know that 'make proto' will ignore them there. The debugparse.h header
- * file is included in includes.h, and includes.h is included in debugparse.c,
- * so all of the pieces "see" each other. I've compiled and tested this,
- * and it does seem to work. It's the same compromise model I used when
- * adding the ubiqx modules into the system, which is why I put it all into
- * the same directory.

- * * Debug message filtering.
- * * I need to add all this to Makefile.in
