Re: [gentoo-dev] Proposal for changes for the next EAPI version

[Pallav Agarwal]

Hi,
You are right, of course.
The target is to standardize something that would encourage maintainers
to actually provide non-upstream scripts to test packages. At the same
time, it should be possible to use those scripts for automated testing
without
human interference.

Even if they are provided independently, not as part of ebuilds, we need a
to have them associated with a particular ebuild if need be as in case of a
bug fix, or many ebuilds in case of basic functionality for all versions of
a
package.

I'm not sure how to deal with eclasses but I guess I'll find out.
