Usage: phpcs [-nwlsaepqvi] [-d key[=value]] [--colors] [--no-colors]
  [--cache[=<cacheFile>]] [--no-cache] [--tab-width=<tabWidth>]
  [--report=<report>] [--report-file=<reportFile>] [--report-<report>=<reportFile>]
  [--report-width=<reportWidth>] [--basepath=<basepath>] [--bootstrap=<bootstrap>]
  [--severity=<severity>] [--error-severity=<severity>] [--warning-severity=<severity>]
  [--runtime-set key value] [--config-set key value] [--config-delete key] [--config-show]
  [--standard=<standard>] [--sniffs=<sniffs>] [--exclude=<sniffs>]
  [--encoding=<encoding>] [--parallel=<processes>] [--generator=<generator>]

 -p    Show progress of the run
 -q    Quiet mode; disables progress and verbose output
 -m    Stop error messages from being recorded
       (saves a lot of memory, but stops many reports from being used)
