 Version 0.10.2 (2006-??-??)
 ---------------------------
 - Changed to generate YYMARKER only when needed or in single pass mode.
-- Added -t switch to force two pass generation.
+- Added -1 switch to force single pass generation and make two pass the default.
 - Fixed -i switch.
 - Added configuration 'yyfill:enable' to allow suppression of YYFILL() blocks.
 - Added tutorial like lessons to re2c.
