xmoto has a configuration option --with-enable-zoom, which could be passed through the ebuild via a package specific use flag "zoom". Reproducible: Always Steps to Reproduce: the following patch can be applied to xmoto-0.3.2.ebuild: 16c16 < IUSE="nls editor" --- > IUSE="nls editor zoom" 42a43,46 > if use zoom > then confzoom="--with-enable-zoom=1" > else confzoom="--with-enable-zoom=0" > fi 45a50 > $confzoom \
why would this need a use flag? Are there any downsides of having it enabled. And why is it not default?
added it unconditionally
