Code review comment for lp:~bac/launchpad/retest

= Summary =

Adding a new utility to make re-running a failed test set easy.

== Proposed fix ==

utilities/retest.py will take the output of a previous run with test failures and
re-run them all. It looks for numbered tests 'stories/foo/01-dosomething.txt' and
will run the entire story directory.

== Pre-implementation notes ==

Talked briefly to Gary who thought the script belongs in utilities.

== Implementation details ==

None.

== Tests ==

Take a previous run with failures and feed it to the script. You can use the email
sent from ec2 as input, e.g.

% utilities/retest.py test.out

== Demo and Q/A ==

As above.
