Tycho is supposed to be a plug-in for maven for building eclipse plug-ins.
I have found various blogs and other articles about it, but the contained links to Tycho are all dead or not accessible for the general public, for example: http://www.sonatype.com/people/2009/04/tycho-040-roadmap/
The only thing I found is a project proposal on the eclipse site, but it doesn't reference any downloads: http://www.eclipse.org/proposals/tycho/
I found a svn repository, but it seems to be extremely dated: http://svn.codehaus.org/m2eclipse/tycho/trunk/
So my question is: where do I get tycho from? Or is it dead and I should stop bothering?
I doubt it's dead, since I found out there is a talk about it on JAX2010 ...
Tycho is not dead at all (it has indeed been submitted to become an Eclipse project) but is now hosted (and actively developed) on github: http://github.com/sonatype/sonatype-tycho
