Thanks!
I see code, take parts frome there for my work purposes and old portmaster
have bad design.
As one more future request.
Current pkg create use only one thread to compress.
I do small set of benchmarks on Ryzen 2700x:

5m42.69s - for compress, compile time ~ 15 minutes. Terrable!!!
49.96s - is mutch better.
Can you try to implement option to chose at least tar/txz, and probably
for txz use "xz -T 0 --compress" ?
