Here is a short report of my work on listers:

Listers I proposed to implement in my proposal -
GNU Lister
Completed and merged
Maven Lister
There are some architectural problems in using two languages in a lister. 
Cran Lister 
Completed and merged
Source forge 
Did research, but no better method other than rsync found, but this approach was used in D261 and abandoned
x.org - 
Discussed this, but no need to make a lister for this
Launchpad 
Did research on it and found the method to make it.

As I could not make all of those that I mentioned in my goal, I did try to make some that were mentioned in the streach goal. Here is a report on those -

Nuget - Did research, but no API to do the work
packagist - Submitted the diff
RubyGems - currently doing some research on it


Cgit - submitted the diff
