Re: [gentoo-user] Stable Python package changes USE flags with ~amd64

[Mickaël Bucas]

I get the following result:
# emerge -pv1 olefile


These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild   R    ] dev-python/olefile-0.46::gentoo  USE="-doc"
PYTHON_TARGETS="python2_7 python3_6 (-pypy3) (-python3_7*) (-python3_8)" 0
KiB
Total: 1 package (1 reinstall), Size of downloads: 0 KiB

It seems to be in line with the interpretation I've come up with.

Best regards
Mickaël Bucas
