INSTALLs in the package and wiki-documentation

[Cube]

I also think there should be a manual included in the package. That's the case with most other software too. Also we can not guarantee, that funny guys do not modify the wiki so that it does not work. Even if we recognise that very fast, this will result in failed installations.
I personally would prefer that there are only the INSTALL-files. I also think it's not that much work for the docu-team to copy changes from the INSTALL-files to the wiki. But in this case that manuals should not be editable by others (I don't know if this is possible with our wiki-software), so that there are always the same instructions in the wiki and in the INSTALL-file. We definitely have to get rid of these two different versions we have right now.
