Hi, I think we can remove this package. HOMEPAGE and SRC_URI are broken and i couldn't find any other upstream. Besides that, powiedz needs /dev/dsp to run, which is from oss, which itself is long deprecated in favor of alsa. It seems like the programm is also only written in polish (powiedz -h), so it's pretty hard to use for non polish speaking persions.
Why would people who aren't speaking Polish, need a speech synthesizer for Polish language?
