n2o ...Not sure if eopkg was played already.
The game is meant for fun and entertainment, it doesn't have rigid rules. Yes, eopkg
was used in OP to start the game, but without any option or sub-command.
Additional arguments, parameters, options, examples, which extend or explain a command are very welcomed.
Next player may choose any final letter he likes from the previous post. G, F, E, D from your post are all good for next move.
How does one search only the current topic?
I simply hit Home key several times until OP is reached, then use browser's key combo for searching (Ctrl+F in Firefox).
