tools/flags

This directory contains tooling for working with chrome://flags entries and part of the automation for expiring flags based on their metadata.

Specifically:

• flags_utils.py: shared code between other tools in this directory
• generate_expired_list.py: build script which produces a generated C++ source file containing a table of all expired flags and their expiration milestones
• generate_unexpire_flags.py: build script which produces C++ source and headers to define the "temporary-unexpire-flags-mX" flags
• list_flags.py: command-line tool to list subsets of flags from metadata; used by automation to file expired-flags bugs.

See ../../docs/flag_expiry.md for more details about flag expiry.
