I thought this must have been through Jason ;-) He is the most active
contributor to bioperl but this just demonstrates how complex bioperl have
got. One person just can not monitor everything. We can easily put blame on
him. He can take it like a man!

To keep everyone informed about commits it is customary to
- be a member of the bioperl mailing list
- announce plans and major code commits to the list
- commit tests, preferable at the same time as code
(There is no more than a paragraph in biodesign.pod, so here is a beginning of
a new tutorial... I just remembered that I wrote something about this in
docbook format more than a year ago, but I can not find it now. If I ever
gave the text to anyone, I'd love to see it again!)
Take a look at a few example test file in the t directory, e.g. t/Spidey.t.
They all contain a BEGIN statement of variable complexity that uses the Test
module and declares how many tests there will be. Test (see 'man Test')
exports function ok() that takes care of printing the output. That output is
all this file should write out when run using 'perl -w t/Spidey.t' or using
make to run the perl test harness (see 'man Test::Harness').
Running these tests periodically enables maintainers see if a change somewhere
has broken some other feature.
You normally start with testing if you can 'use' your new module, then that
you can create an object and then proceed by testing at least all the public
methods. Data files can be put into t/data. You can have output from your
test script, but it should clean up all new files at exit (do that within END

If there is more interest, it would be cool to have an abstaction layer and be
able to output more formats.
I guess we can not do anything to the PostScript::TextBloc dependency here.

Is the use of Set::Scalar really necessary? It is yet an other dependency,
although I do like it myself, and it might turn out to be useful to other
modules, too, in the future.

They are in. No real hurry with the tests.
