-# To integrate dartanalyze with our build system, we take an input file, run
-# the analyzer on it, and write a stamp file if it passed.
-
-# This script analyzes a set of entrypoints specified with the --entrypoints
-# flag. The location of the Dart SDK must be specified with the --dart-sdk
-# flag. A stamp file can optionally be written with the location given by the
-# --stamp-file flag. Any command line arguments not recognized by this script
-# are passed on to the Dart analyzer.
