[news.eclipse.tools.emf] Re: extending eType(s)

Hi Ed,

thanks - looks promising ... :)

How do I get the sources for a specific emf build, e.g., 2.5.0 
(2009/06/16), that I use into my package explorer as java project to 
modify the sources and (re-)build the complete (&modified) emf package?

I downloaded the complete sdk 
http://www.eclipse.org/modeling/download.php?file=/modeling/emf/emf/downloads/drops/2.5.0/R200906151043/emf-xsd-SDK-2.5.0.zip
but in this version I can only rebuild some classes and (maybe) put them 
back into the jar. Same applies to the sources .zip.

I downloaded the (tagged 2009/06/16 - assuming this is 2.5.0 and not 
2.6.0?) sources from dev.eclipse.org which seems to be the "right" place 
but I can't export the org.eclipse.emf.sdk-feature (it is not shown in 
the exportable feature list of the export wizard)?

Greetings,

	Ralf
