Thanks, Michael. For what it's worth, I actually do all of my scion-server development in EclipseFP to prove that I can proverbially "eat my own dog food". -scooter On Tue, Feb 1, 2011 at 2:49 AM, Michael Diamond <mdi...@wi...>wrote: > Hi guys, > > After setting up three computers to use EclipseFP, I wrote the following to > help others through the configuration, and thought I'd share this with you. > Feel free to use any or all of this anywhere you find it helpful.
