lilypond.org - file storage

[Phil Holmes]

OK - it looks like lilypond.org is now back, and I can SSH to it again.  
However, I still can't complete the upload of files because of lack of 
disk space on the server.  I've emailed the admin but no response yet.

That said, we do seem to be storing an enormous amount of potentially 
unneeded stuff there.  Do we really need _all_ the 2.15 and 2.17 
documentation stored there? 
(http://lilypond.org/download/binaries/documentation/)  And all the test 
output? (http://lilypond.org/download/binaries/test-output/)  Please look 
at http://lilypond.org/download/binaries/ and let me know whether you 
think we can delete some of that, or potentially archive it elsewhere.

Thanks.
