[rules-dev] Stretching spreadsheets

[Wolfgang Laun]

I'll clean this one up, too.

My objective will be to
- inform users unambiguously about mistakes and how to correct them,
- recover useful features,
- be reticent w.r.t. deprecated features (duration!),
- document the result

PS.: The December 6 issue of Time magazine contains the remarkable sentence:
"...an invention [...] intended to simplify the [...] process by making it
more complicated". Well, well, well,...
