Yep. The idea is with eggs is that each package should load the 
configuration of all its dependencies first before making any registrations.

Exactly. Those ZCML "slugs" in etc/package-includes where a horrible 
mess and confused most newbies. They were problem maker #1 in all 
trainings (people simply forgot them).

site.zcml (still) is the root ZCML file (zope.conf refers to it, in 
fact, that's why). It includes all other ZCML files. Typically it only 
has to include the application package ("books" in your case) now 
because that application is in charge of loading all the dependencies 
(which happen to bring up most of Zope).

Great to hear that.

You were on the right track. Unfortunately, that's not enough. 
zope.app.apidoc doesn't make sure its dependnecies are loaded. (We're 
not completely there yet with the eggification in that regard).

zopeproject 0.4.1 actually enables APIDoc by default. You might want to 
look at the apidoc.zcml it generates in the top level sandbox directory. 
TO get the new zopeproject version, use

    easy_install -U zopeproject

That's weird. This shouldn't be APIDoc related. This error actually 
occurs when you try to go to the "Server Control" screen of ++etc++process.

Zope isn't in charge of the process anymore. bin/paster is. We should 
really just get rid of that screen, or at least make it handle this case 
gracefully.

Ah, thanks for bringing this up. You can use a logging middleware, such 
as Paste#translogger. Simply edit 'deploy.ini' and change it to read::


[filter-app:main]
use = egg:Paste#translogger
next = zope

[app:zope]
use = egg:HelloWorld

[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 8080
