 # To integrate dartanalyze with out build system, we take an input file, run
 # the analyzer on it, and write a stamp file if it passed.
 #
 # The first argument to this script is a reference to this build's gen
 # directory, which we treat as the package root. The second is the stamp file
 # to touch if we succeed. The rest are passed to the analyzer verbatim.
