quote of Aho from an interview ---
"We [Aho and Kernighan] had created a grammatical specification for AWK but
hadn't yet created the full run-time environment. Weinberger came along
and said 'hey, this looks like a language I could use myself', and within
a week he created a working run time for AWK."
