Thanks! Here is the updated help description in the script:

DESCRIPTION = f"""
For Intel CPUs, update the microcode revisions that determine
X86_BUG_OLD_MICROCODE.

This script is intended to be run in response to releases of the
official Intel microcode GitHub repository:
https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files.git

It takes the Intel microcode files as input and uses iucode-tool to
extract the revision information. It prints the output in the format
expected by intel-ucode-defs.h.

Usage:
    ./{script} /path/to/microcode/files > /path/to/intel-ucode-defs.h

Typically, someone at Intel would see a new release, run this script,
refresh the intel-ucode-defs.h file, and send a patch upstream to update
the mainline and stable versions.

If there are no other comments, I'll send out a revised version with an
updated commit message early next week.
