Yes, independently of what we set as default on the PluginBundle, it is
still possible to have the values changed on a per distribution basis.
Something like:

    [@BioPerl]
    -remove = ExecDir

    [ExecDir]
    -dir = scripts

I don't think we need to have them symlinked.  We can easily set "scripts/"
as the default for [ExecDir] on our PluginBundle.  But before we change the
default, why are we using something which is far less common?  Why are we
not using "bin/" instead?  If we had the bioperl programs in "bin/" rather
than "scripts/" we would not have had this problem in the first place.

So I'm proposing that as we move modules from bioperl-live into the smaller
distributions, we also move them to a "bin/" directory as part of the
configuration for dzil (no symlinking required).  This may prevent more
problems in the future with other tools, by having things where they are most
expected to be, and not having to remember they are somewhere else.

By the way, I have already done this on the Bio-EUtilities distribution
which is where I noticed the problem [1].

Isn't the file extension removed during installation of bioperl?
I remember that the "bp_" was added automatically, a step which we
dropped in favour of simply having the files already with the "bp_".
I thought that it was the same with the file extension.
