Accepting request 343469 from home:frispete:tools
Hi Andreas,
thanks for catching the missed parts.
To be honest, I don't get the meaning of of the 2nd sentence of the

a couple of GNU tools (code and description). ;)
Cheers,
Pete
- fix conversion: spell the missed parts correctly
- add xznew{,.1}, converted from bznew
