Copy the trace module here from Tools/scripts.
There are some problems with this module, but the tool works for
simple tasks and no one else has volunteered a better code coverage
tool. Should cleanup and document before the beta release.

+-t, --trace Print each line to sys.stdout before it is executed.
+-c, --count Count the number of times each line is executed

+ See also `--coverdir', `--file', `--no-report' below.
+-r, --report Generate a report from a counts file; do not execute

+ 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
