+Usage: ${0##*/} [--help] [--only-changed-files] [--apply-format-changes] [BASE_REV]
+
+If the first argument given on the command line is the option --help or -h,
+this program prints usage information and then exits.
+
+With no arguments, this runs multiple checks on the code base. These tests
+are based on the programs in the checks/ subdirectory.
+
+If --apply-format-changes is specified, the flag --apply will be passed to
+check/format-incremental to apply the format changes suggested by the
+formatter.
+
+You can specify a base git revision to compare against (i.e., to use when
+determining whether or not a file is considered to have changed). If given,
+the argument BASE_REV is passed on to tests that can use it, such as
+check/pytest-and-incremental-coverage."
