--- Notes --- \n\
- All builds use same output directory unless overridden with \n\
 \t ALT_OUTPUTDIR=<dir>, changing from product to fastdebug you may want \n\
 \t to use the clean target first. \n\
- JDK_IMPORT_PATH must refer to a compatible build, not all past promoted \n\
 \t builds or previous release JDK builds will work. \n\
- The 'debug' target and 'import_debug' only works when a debug promoted \n\
 \t build is available, and they currently are not. \n\
- The fastest builds have been when the workspace and the BOOTDIR are on \n\
 \t local disk. \n\
