[tycho-user] How to use targetPlatformAsSource

[laeubi@xxxxxxxxxxxxxx]

I found here[1] that there is an option named 'targetPlatformAsSource', 
but I can't find any further refrence/documentation/example how to use 
it. I would have exspected that tycho then would read the sources from 
the targetplatform but that does not seems to work (error is: No 
repository provided as 'source')
