Querying the code is more reliable than querying my memory. Let me guide 
you.

- In an updated Cuis Image, open a File List. Navigate to FFI.pck. 
Select it. Click on (code). This opens a browser on the package code 
without actually loading it.
- Open a web browser on http://source.squeak.org/FFI . Download the last 
version of each Monticello package.
- In Cuis, open a File List, navigate to the .mcz files. Select each 
one, and click on (code). Yes, Cuis can show you the contents of 
Monticello packages.

Now it is rather easy to see that FFI.pck includes the stuff in 
FFI-Kernel and FFI-Pools. No platform specific stuff is included.

So, you think that the Cuis package doesn't include some newer cool 
updates. (I haven't been following  Torsten's work.) Ok. Let's see. Now 
do install the FFI.pck. Select FFI-Kernel.mcz. This time select 
contents. A browser that shows a list of methods opens. Now select any 
method. Mhh. Well, the package uses the Cr line separators, not Lf as in 
Cuis. No big deal. Click on (linePrettyDifs). Now line separators and 
formatting are not an issue when comparing code. Click (deselectAll) Now 
do 'select methods equivalent to current' (via right click menu on the 
methods list) and 'remove selected methods'.

Now you can compare the differences, see what changes were needed for 
Cuis, see what has been changed recently in the Squeak package, etc.

Cheers,
Juan Vuletich
