The missing NEWS entries correspond to changes that were made before 3.1.3, but
I think it’s not usual to edit entries of released versions, so I put them at
the top.

-Command Line Usage
+Command-Line Usage
 ------------------
 
 The :mod:`trace` module can be invoked from the command line.  It can be as
 simple as ::
 
-   python -m trace --count somefile.py ...
+   python -m trace --count -C . somefile.py ...
 
-The above will generate annotated listings of all Python modules imported during
-the execution of :file:`somefile.py`.
+The above will execute :file:`somefile.py` and generate annotated listings of
+all Python modules imported during the execution into the current directory.
 
-The following command-line arguments are supported:
+.. program:: trace
+
+.. cmdoption:: --help
+
+   Display usage and exit.
+
+.. cmdoption:: --version
+
+   Display the version of the module and exit.
+
+Main options
+^^^^^^^^^^^^
+
+At least one of the following options must be specified when invoking
+:mod:`trace`.  The :option:`--listfuncs <-l>` option is mutually exclusive with
+the :option:`--trace <-t>` and :option:`--counts <-c>` options . When
+:option:`--listfuncs <-l>` is provided, neither :option:`--counts <-c>` nor
+:option:`--trace <-t>` are accepted, and vice versa.
+
+.. program:: trace
+
+.. cmdoption:: -c, --count
+
+   Produce a set of annotated listing files upon program completion that shows
+   how many times each statement was executed.  See also
+   :option:`--coverdir <-C>`, :option:`--file <-f>` and
+   :option:`--no-report <-R>` below.
+
+.. cmdoption:: -t, --trace
 
-:option:`--trace`, :option:`-t`
    Display lines as they are executed.
 
-:option:`--count`, :option:`-c`
-   Produce a set of  annotated listing files upon program completion that shows how
-   many times each statement was executed.
+.. cmdoption:: -l, --listfuncs
+
+   Display the functions executed by running the program.
+
+.. cmdoption:: -r, --report
 
-:option:`--report`, :option:`-r`
    Produce an annotated list from an earlier program run that used the
-   :option:`--count` and :option:`--file` arguments.
+   :option:`--count <-c>` and :option:`--file <-f>` option.  This does not
+   execute any code.
 
-:option:`--no-report`, :option:`-R`
-   Do not generate annotated listings.  This is useful if you intend to make
-   several runs with :option:`--count` then produce a single set of annotated
-   listings at the end.
+.. cmdoption:: -T, --trackcalls
+
+   Display the calling relationships exposed by running the program.
+
+Modifiers
+^^^^^^^^^
+
+.. program:: trace
 
-:option:`--listfuncs`, :option:`-l`
-   List the functions executed by running the program.
+.. cmdoption:: -f, --file=<file>
 
-:option:`--trackcalls`, :option:`-T`
-   Generate calling relationships exposed by running the program.
+   Name of a file to accumulate counts over several tracing runs.  Should be
+   used with the :option:`--count <-c>` option.
 
-:option:`--file`, :option:`-f`
-   Name a file containing (or to contain) counts.
+.. cmdoption:: -C, --coverdir=<dir>
 
-:option:`--coverdir`, :option:`-C`
-   Name a directory in which to save annotated listing files.
+   Directory where the report files go.  The coverage report for
+   ``package.module`` is written to file :file:`{dir}/{package}/{module}.cover`.
+
+.. cmdoption:: -m, --missing
 
-:option:`--missing`, :option:`-m`
    When generating annotated listings, mark lines which were not executed with
-   '``>>>>>>``'.
+   ``>>>>>>``.
+
+.. cmdoption:: -s, --summary
+
+   When using :option:`--count <-c>` or :option:`--report <-r>`, write a brief
+   summary to stdout for each file processed.
+
+.. cmdoption:: -R, --no-report
+
+   Do not generate annotated listings.  This is useful if you intend to make
+   several runs with :option:`--count <-c>`, and then produce a single set of
+   annotated listings at the end.
+
+.. cmdoption:: -g, --timing
+
+   Prefix each line with the time since the program started.  Only used while
+   tracing.
 
-:option:`--summary`, :option:`-s`
-   When using :option:`--count` or :option:`--report`, write a brief summary to
-   stdout for each file processed.
+Filters
+^^^^^^^
 
-:option:`--ignore-module`
-   Accepts comma separated list of module names. Ignore each of the named
-   module and its submodules (if it is a package).  May be given
-   multiple times.
+These options may be repeated multiple times.
 
-:option:`--ignore-dir`
-   Ignore all modules and packages in the named directory and subdirectories
-   (multiple directories can be joined by os.pathsep).  May be given multiple
-   times.
+.. program:: trace
 
+.. cmdoption:: --ignore-module=<mod>
+
+   Ignore each of the given module names and its submodules (if it is a
+   package).  The argument can be a list of names separated by a comma.
+
+.. cmdoption:: --ignore-dir=<dir>
+
+   Ignore all modules and packages in the named directory and subdirectories.
+   The argument can be a list of directories separated by :data:`os.pathsep`.

+
+   Create an object to trace execution of a single statement or expression.  All
+   parameters are optional.  *count* enables counting of line numbers.  *trace*
+   enables line execution tracing.  *countfuncs* enables listing of the
+   functions called during the run.  *countcallers* enables call relationship
+   tracking.  *ignoremods* is a list of modules or packages to ignore.
+   *ignoredirs* is a list of directories whose modules or packages should be
+   ignored.  *infile* is the name of the file from which to read stored count
+   information.  *outfile* is the name of the file in which to write updated
+   count information.  *timing* enables a timestamp relative to when tracing was
+   started to be displayed.
+
+    .. method:: run(cmd)
+
+       Execute the command and gather statistics from the execution with
+       the current tracing parameters.  *cmd* must be a string or code object,
+       suitable for passing into :func:`exec`.

-.. method:: Trace.run(cmd)
+    .. method:: results()
 
-   Run *cmd* under control of the Trace object with the current tracing parameters.
+       Return a :class:`CoverageResults` object that contains the cumulative
+       results of all previous calls to ``run``, ``runctx`` and ``runfunc``

+       trace results.
 
+.. class:: CoverageResults
 
-.. method:: Trace.runctx(cmd, globals=None, locals=None)
+   A container for coverage results, created by :meth:`Trace.results`.  Should
+   not be created directly by the user.
 
-   Run *cmd* under control of the Trace object with the current tracing parameters
-   in the defined global and local environments.  If not defined, *globals* and
-   *locals* default to empty dictionaries.
+    .. method:: update(other)

-.. method:: Trace.runfunc(func, *args, **kwds)
+    .. method:: write_results(show_missing=True, summary=False, coverdir=None)
 
-   Call *func* with the given arguments under control of the :class:`Trace` object
-   with the current tracing parameters.
+       Write coverage results.  Set *show_missing* to show lines that had no
+       hits.  Set *summary* to include in the output the coverage summary per
+       module.  *coverdir* specifies the directory into which the coverage
+       result files will be output.  If ``None``, the results for each source
+       file are placed in its directory.
