...means that within the next 12 hours or so we should see Emms available on elpa. When you do see it, please test it as much as possible, provide feedback, and of course preferably patches. The Emms git repo now has an elpa branch: http://git.savannah.gnu.org/cgit/emms.git/log/?h=elpa ...and on that branch things look different. This is the branch that is currently being pushed out to gnu/elpa. Since Emms is a big elisp package it has its own branch on gnu/elpa. Once we see that Emms is working on gnu/elpa we will notify melpa, and then synchronize the Emms master branch with the elpa branch. -- "Cut your own wood and it will warm you twice"
