Hi there, during grok development we recently experienced some trouble with the zope.app.error package. We distribute the list on `http://download.zope.org/distribution` as sources list for grokproject, so that projects created with that tool, by default lookup this list for available eggs/packages. On this list the 3.5.1 release of zope.app.error is missing (older releases are available), which makes projects created with grokproject using an older release of zope.app.error, which in turn leads to errors. A bit annoying. To understand the sources lookup process better, I would like to know: Is there a special reason, why zope.app.error 3.5.1 is not listed on the above distribution list (while older versions are listed)? What is the recommended sources list for looking up zope eggs during buildout, anyway? There is at least also the `ppix` 'listing' on download.zope.org (which already provides zope.app.error 3.5.1). What's the difference in terms of completeness and up-to-dateness of listed packages? Sorry, if this are dumb questions and thanks in advance, -- Uli
