It would be interesting to see how many of these are actual dependencies,
and how many could be solved in other ways - many of the Squeak classes
mentioned below, for example, could probably be gotten rid of:

This seems to only be used by the Wiki example, which (sorry goran) is
pretty messy code that probably wants to be rewritten anyway (actually,
I'm still waiting for news of the SmallWiki stuff from Bern... Lukas?).

This is because of #printStringLimitedTo:, I assume.  What is the VW idiom
for this?  How to VW inspectors avoid showing long (or infinite)
printStrings?

This class only makes sense in a Squeak context - the one subclass
of it can just be ignored.

It probably makes sense to introduce a Seaside-specific way of generating
IDs anyway, that can be used in both Squeak and VW.

Hm, odd that VW didn't have this already.

Anyway, just thinking out loud - but I would definitely like to make the
process of porting to VW smoother (or rather, of keeping the VW port up to
date).  The syntax issues are trivial - what I'll probably do is add a
Rosetta exporter to Monticello, which should then make it easy to produce
a .pst file or whatever.  It might also be a good idea to separate the
stuff that's obviously Squeak-specific (WABrowser, WAMemoryUse,
WAScreenshot, at least) into a separate package - for this to work I guess
the toolbar could be adapted so that tools are registered with it instead
of hard coded.

What else would be useful?
