This is awesome news :)

I maintain dependency graphs for all zope packages included in Zope2
trunk at Those should be correct
covering the state from yesterday before your release-marathon. But I
think the depdendencies didn't change for any of the packages I cover.

If you want to generate those yourself, to get an easy graphical way of
understanding the mess, then the following steps should get you there:

easy_install tl.eggdeps

Thanks Thomas! This parses the requires.txt in the egg_info folders. So
make sure they are updated after you edit any files. Run:

eggdeps -x -d -i setuptools >

[-x ignores extras, -d specifies a dot file as output, -i ignores

In order to make the graphs more readable you can remove the transitive
dependency edges from the graph:

And finally produce a nice visual graph:

dot -Tjpeg >

[-Tsvg or -Tpng should work as well]

tred and dot are part of graphviz. If you happen to run Mac OS and use
MacPorts you need to install graphviz-devel instead of the graphviz port
for tred to work. In the latest stable graphviz port tred is broken.
