Few years ago I released a first version of Whiskers together with buildout.sendpickedversions . It's about the time to push new version out. What is Whiskers? Whiskers is a Pyramid web application which stores information about your buildouts so that you don't have to manually check what they contain. All the data to Whiskers is transferred by buildout.sendpickedversions - an buildout extension which keeps track of packages your buildout uses and sends the data in json-format to Whiskers-server. Reason for Whiskers? Main reason for me to develop Whiskers was based on the need of knowing what packages I have in our servers. I'm working at the University of Jyväskylä and part of my job is to maintain our Plone instances. We have about 100 Plone instances with slightly varying setup. If we needed a new version of some specific package it meant lots of work to have a list of Plone-sites which needed the update. With Whiskers I know what to update after few clicks.
