[mmt-dev] ATL downloads cleanup

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi William

I was waiting for your RC3 before cleaning up the obsolete 
downloads/modeling/m2m but there seems to be no ATL RC3, so I've tried 
cleaning up anyway.

I moved the missing ATL RC1 from modeling/m2m to mmt.

Rather than delete outright, I moved downloads/modeling/m2m/atl to 
/home/data/httpd/archive.eclipse.org/mmt/atl but ran into permission 
errors on the delete so half the deletes failed.

The overall size is huge: 1.2G was copied, of which 0.5G was not deleted.

I see no point keeping milestones and release candidates for previous 
releases, and little point in more than a couple of milestones plus 
release candidates for the current release.

I see little point keeping more than the final service release for the 
last couple of historic builds.

So on downloads, it is worth trimming to 3.3.0RC2, 3.3.0RC1, 3.2.1, 3.1.1

and on archive 3.2.0, 3.1.0, 3.0.*, 2.*, 1.*.

Please try to keep N-builds and I-builds under control.

My move saved 0.7G. Using your permissions you can save another 0.5G 
from m2m/atl. Tidying up mmt/atl may save another 0.8G. Tidying up the 
archive should trim it by at least 0.5G as well.

All in all, ATL should be able to add 2 G to the 55 G saved by other 
projects. Rather a large number for a project with quite modest download 
size.

I'll investigate why the archives do not show up on the Downloads page 
in the same way as e.g. MDT/OCL; may be I just need to wait for a slow 
cache refresh.
