+ To enable boot performance logging, set the environment variable 
+ UNITY_BOOTLOG_FILENAME to a path to the log file and make sure unity is built
+ with --enable-testing. eg:
+ UNITY_BOOTLOG_FILENAME=/tmp/unity.log unity -p
+ 
+ you can then produce a bootchart with this by running the tools/makebootchart.py
+ script:
+ ./tools/makebootchart.py --input=/tmp/unity.log --output=/tmp/unity.svg
