All 1.8 stuff goes into one file. All 1.9 in another. So there is
clear separation. When running Ruby 1.8 only that file gets
'required'. In pseudo-code.

if ruby_version<1.9
  if !isjvm?
    require 'bio/ruby-1.8'
  else
    require 'bio/ruby-jvm'
  end
else
  require 'bio/ruby-1.9'
end

Implementation specific stuff will go into these files (if possible).
Say you have a different println implementation, rather than
sprinkling the code base with:

if ruby_version<1.9
  if !isjvm?
    println_1 ...
  else
    println_2 ...
  end
else
  println_3 ...
end

You would 'hide' that in the architecture files. So you just get one
call in the source tree:

  println_arch ...

with implementation in the different 'architecture' files.
