paster_commands: remove unused imports Remove some unused imports, using 'autoflake' followed by manual redacting. find kallithea/lib/paster_commands/ -name "*.py" \ | xargs autoflake --remove-all-unused-imports -i This same command could be applied gradually throughout the code base as areas are touched. Since autoflake may be too greedy in special cases, it is more difficult to do a big-bang action over all code.
