So GNU Pies fata ma nnwumayɛbea ahorow?

Yiw. GNU Pies ayɛ GNU Dwumadie no fã mfeɛ pii na wɔayɛ ama nhyehyɛeɛ a ɛbɛkyɛ, ayɛyɛdeɛ-grade nhyehyɛeɛ sohwɛ.

So GNU Pies betumi ahwɛ nnwuma pii so prɛko pɛ?

Ɛyɛ saa koraa. Wubetumi akyerɛkyerɛ component blocks dodow a ɛho hia mu wɔ nhyehyɛe fael biako mu. Pies bɛhyɛ aseɛ, ahwɛ, na wɔasan ahyɛ ɔsom biara ase wɔ wɔn ankasa mu.
