How should I pronounce "TeX"?

The 'X' is "really" the Greek letter Chi, and is pronounced by English-speakers either a bit like the 'ch' in the Scots word 'loch' ([x] in the IPA) or like 'k'. It definitely is not pronounced 'ks' (the Greek letter with that sound doesn't look remotely like the Latin alphabet 'X').
