My major beef with zc.buildout is perhaps actually a problem with the
recipes nearly everybody uses:  they blow away hand-edited stuff without
warning.  In particular, changes to things like the zope.conf file get
zapped, because buildout (or the recipe) thinks that the file is its own
personal property.

My sense is that zc.buildout's focus on "production deployment" usecass
is the source of a lot of my frustration with it as a developer:  I
expect to "inhabit" the environment it creates, which is completely
irrelvant in a production rollout.
