Subject Re: svn commit: r1131410 - /lucene/dev/branches/branch_3x/dev-tools/scripts/poll-mirrors.pl
Date Sat, 04 Jun 2011 15:44:11 GMT
Thanks to both you and Mike (and everyone else working on this
automation so far) for adding these scripts... things are getting
easier!

Also, I'm especially happy seeing the benefits the javadocs warnings
checker and license checker added in 3.1... this stuff really saves a
ton of time.
