To install the GMF SDK and all its prereqs from the Ganymede Update site into any folder then link to it using a .link file in the dropins folder, run this:

#!/bin/bash
workspace=/tmp/workspace-clean-34
eclipseroot=~/eclipse/34clean/p2director
installTargetFeatureGroup=org.eclipse.gmf.sdk.feature.group
bundlepoolDir=$eclipseroot/${installTargetFeatureGroup}/eclipse

pushd $eclipseroot >/dev/null
if [[ $# -eq 0 ]]; then
	rm -fr eclipse $workspace $bundlepoolDir
	eclipse=eclipse-SDK-3.4-linux-gtk.tar.gz
	echo "[`date +%H:%M:%S`] Unpack $eclipse ...";
	tar xzf $eclipse
fi
