Subject: Re: ARGV || something

In Ruby 1.8, ARGV is always an array. Since the truth value of an empty
array is still "true", you can't just use '||' to provide defaults.

It's a bit longer, but your code should work if you do the following:

components = (ARGV.size > 0 ? ARGV : %w[ Adjoint Design UN3D_90 GetGrad
GridMove HRefine LibF90 Mixed Party PHYSICS_MODULES Rad ])
