"Finally home again", just to discover that I have not 'bdwrite'
available on my workstations upgraded with the latest 31. Oct 2022 CinGG
appimages.
Therefore I wonder if CinGG Appimage not provide and make it possible to
run bdwrite from command line (similar like no ffmpeg) without a single
user build?
If this is the case, the recent testing I have done with bdwrite on my
ultrabook, has unhappily been with a 2 year old and possibly outdated
version from the last Cin 5.1 Package version dated October 31, 2020 for
openSUSE. In lack of other ways to verify or querry bdwrite's version:
# which bdwrite
