Hello ghc-devs,

I would like to delete the file sync-all from the GHC repository. It should not have been necessary to use it for about a year now. 

Please speak up if you want those 1000 lines of buggy Perl a.k.a. sync-all to stay for some reason, or if you have questions about a certain git submodules workflow. 

The source code (./boot no longer suggests it) and the wiki are already sync-all free, except for a few historical pages.

Discussion period: 1 month.

Thomas
