        `data_file` is the base name of the data file to use, defaulting to
        ".coverage".  `data_suffix` is appended (with a dot) to `data_file` to
        create the final file name.  If `data_suffix` is simply True, then a
        suffix is created with the machine and process identity included.

        `cover_pylib` is a boolean determining whether Python code installed
        with the Python interpreter is measured.  This includes the Python
        standard library and any packages installed with the interpreter.

        If `auto_data` is true, then any existing data file will be read when
        coverage measurement starts, and data will be saved automatically when
        measurement stops.

        If `timid` is true, then a slower and simpler trace function will be
        used.  This is important for some environments where manipulation of
        tracing functions breaks the faster trace function.

        If `branch` is true, then branch coverage will be measured in addition
        to the usual statement coverage.

        `config_file` determines what config file to read.  If it is a string,
        it is the name of the config file to read.  If it is True, then a
        standard file is read (".coveragerc").  If it is False, then no file is
        read.

        `source` is a list of file paths or package names.  Only code located
        in the trees indicated by the file paths or package names will be
        measured.

        `include` and `omit` are lists of filename patterns. Files that match
        `include` will be measured, files that match `omit` will not.  Each
        will also accept a single string argument.

        `debug` is a list of strings indicating what debugging information is
        desired. `debug_file` is the file to write debug messages to,
        defaulting to stderr.

        `concurrency` is a string indicating the concurrency library being used
        in the measured code.  Without this, coverage.py will get incorrect
        results.  Valid strings are "greenlet", "eventlet", "gevent", or
        "thread" (the default).
