/*
* Convert Intel microcode.dat into individual ucode files
* named: intel-ucode/$family-$model-$stepping
*
* The subdir intel-ucode/ is created in the current working
* directory. We get multiple ucodes in the same file, so they
* are appended to an existing file. Make sure the directory
* is empty before every run of the converter.
