Oh and if you're updating the readme, is it possible that the wget syntax isn't correct?
I'm not very familiar to linux yet, but this looks very funny to me:

Quote:

wget -O - http://upp.invothink.com/dolik.rce.gpg.key | sudo apt-key add -

What I mean is the "-" without any parameter? (like the O at -O)

//edit: Nevermind, got the solution. -O - is printing to STDOUT and - is bringing it to STDIN, right?

Yes, exactly Smile

The -O is a parameter specifying where the output should be stored. It is usually a file, but in this case it is "-" which is common shorthand for standard output in POSIX environments, which is then routed through pipe to the apt-key program. The same could be also written as -O /dev/stdout, but that is bit more verbose and I am too lazy too type Very Happy
