Before 2.2.6 the dar ebuild installed /usr/share/dar/dar_par.dcf /usr/share/dar/dar_par_create.duc /usr/share/dar/dar_par_test.duc These are ready to use examples of how to integrate Parchive and since they aren't trivial to write yourself, it's really nice to have them provided. But since 2.2.6 they don't get installed even with "doc examples" in USE, because the ebuild deletes most stuff in /usr/share/dar in src_install. It would be great if this could be changed back to the old behaviour.
sorry for delay. it fixed in dar-2.3.3.
