-"""Wraps jscoverage to instrument a single file more efficently.
-
-JScoverage crawls directories recursively to copy and instrument everything
-under a directory. This turns out to be too slow for our use, because our
-generated .js files live in directories with > 100K files. Even though
-jscoverage has a flag ('--exclude') to skip some files for
-instrumentation/copying, it stills crawls recursively everything under the
-directory.
-
-This script is a simple wrap on top of jscoverage. It creates a temporary
-directory, copies the file we want to instrument alone, and runs jscoverage
-within this small directory.
