"""
`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"). 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. Valid strings are "greenlet", "eventlet", "gevent",
"multiprocessing", or "thread" (the default).
