Thanks for the link and your effort, this is somehow helpful. However, I have
the following suggestions (regarding the buildout part):
1) Like so often in the Zope world, I miss the "big picture" - I (or better,
the newbies) don't really know what's happening here. What exactly is
buildout? What's an Egg/setuptools/PyPi? (references would also help here).
I'd very much appreciate illustrations, something like simple block diagrams
that show, for example, how buildout pulls together needed modules.
2) Much content is in a recipe-like fashion, for instance on page 4 you
specify in install_requires "zope.app.zcmlfiles, zope.app.twisted and
zope.app.securitypolicy". Why do you use exactly these modules? Are they the
very minimum for Zope3? What about other modules, e.g. formlib? Is there some
overview for available modules?
3) Page 5 and 6 is not understandable for newcomers - they can simply cut &
paste the code but they will never know what happens here as they lack the
knowledge of e.g. what a ZopeSecurityPolicy is, how the ZopeDB works etc. I,
too, don't really know where my instance data will be situated (var/, log/,
site-packages/ etc/). I think things would be a lot easier if the user can
call some "mkzopeinstance" script as in the tarballs that does this stuff for
4) When using eggs, packages are normally kept in an ".egg" file, therefore I
can't have a look at the Zope3 source code - which is inevitable for Zope3
development. AFAIK, there's some option that lets easy_install decompress the
eggs and install it in plain text, is this also the case in your book?
5) The book gives me the overall impression that installing Zope3 the
egg-style way requires me to do quite some really complicated stuff I even
don't really understand in full depth. Compared to that, installing Zope3
from the tarball is a lot easier - it's basically about "./configure, make
install, mkzopeinstance", which is not complicated at all.
