I'd suggest that we move away from bioperl-cext (is neat, but not that
useful) and concentrate on wrapping EMBOSS things. I just think that's
probably stabler and easier to install.

Once you've got the wrappers, building this sort of application is easy
right.... it would be nice to have it as an object.
