I now speak fluent emacs, xemacs, ed, ex, vi, vim, and gvim. I AM A GOLDEN GOD! BWAHAHAHAHAHAHAHA. I feel TECO would be a foolish frivolity. ed is the standard. What further proof do you need?

Of course I'd have more pride in the matter if I was also fluent in sh, perl, python, sed, awk, lex, yacc and 87 other unix tools, but I'm young yet.
