`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 configuration file to read:
* If it is ".coveragerc", it is interpreted as if it were True,
for backward compatibility.
* If it is a string, it is the name of the file to read. If the
file can't be read, it is an error.
* If it is True, then a few standard files names are tried
(".coveragerc", "setup.cfg", "tox.ini"). It is not an error for
these files to not be found.
* If it is False, then no configuration 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 file name 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.
`concurrency` is a string indicating the concurrency library being used
in the measured code. Without this, coverage.py will get incorrect
results if these libraries are in use. Valid strings are "greenlet",
"eventlet", "gevent", "multiprocessing", or "thread" (the default).
This can also be a list of these strings.
