+--help Display this help then exit.

+
+Otherwise, exactly one of the following three options must be given:
+-t, --trace Print each line to sys.stdout before it is executed.
+-c, --count Count the number of times each line is executed
+ and write the counts to <module>.cover for each
+ module executed, in the module's directory.
+ See also `--coverdir', `--file', `--no-report' below.
+-l, --listfuncs Keep track of which functions are executed at least
+ once and write the results to sys.stdout after the
+ program exits.
+-T, --trackcalls Keep track of caller/called pairs and write the
+ results to sys.stdout after the program exits.
+-r, --report Generate a report from a counts file; do not execute
+ any code. `--file' must specify the results file to
+ read, which must have been created in a previous run
+ with `--count --file=FILE'.
+
+Modifiers:
+-f, --file=<file> File to accumulate counts over several runs.
+-R, --no-report Do not generate the coverage report files.
+ Useful if you want to accumulate over several runs.
+-C, --coverdir=<dir> Directory where the report files. The coverage
+ report for <package>.<module> is written to file
+ <dir>/<package>/<module>.cover.
+-m, --missing Annotate executable lines that were not executed
+ with '>>>>>> '.
+-s, --summary Write a brief summary on stdout for each file.
+ (Can only be used with --count or --report.)
+-g, --timing Prefix each line with the time since the program started.
+ Only used while tracing.
+
+Filters, may be repeated multiple times:
+--ignore-module=<mod> Ignore the given module(s) and its submodules
+ (if it is a package). Accepts comma separated
+ list of module names
+--ignore-dir=<dir> Ignore files in the given directory (multiple
+ directories can be joined by os.pathsep).
