Hello,
gtk is a global use flag [1], gtk2 and gtk3 are used in metadata.xml [2].
Is there a consensus how to use these flags if an app provides gtk2
and gtk3 gui in parallel or exclusive?
'gtk' uses best possible version as defined by the package maintainer
'gtk3' is a special flag that is used when package supports both gtk and
gtk3 at the same time, and matches the criteria of sanity which is a)
it's an library that is used by multiple programs b) is not easy to
split, which would otherwise be preferred over using the USE flag
'gtk2' is never required, those matching it down from the list have weak
design which goes against every other ebuild in tree, but is still
package maintainers decision
special flags like 'IUSE="+deprecated"' can be used if there is a need
to enable the old GTK+ implementation by default, but still provide the
new one, in programs. like if enabling GTK+3 instead of GTK+2 would
disable you from using flash plug-in in a browser, would qualify in.
imho :)
