echangelog was updated to automatically verify + update the header of the ChangeLog file. this is useful when packages get moved, or when ChangeLog files get copied. specifically, i'm referring to the first line: # ChangeLog for dev-util/pkg-config-lite echangelog will make sure that atom always matches the local package and update it if it doesn't.
This can likely be closed as invalid or something as Changelogs are gone. Likely echangelog should be as well.
repoman support has been removed per bug 835013. Please file a new bug (or, I suppose, reopen this one) if you feel this check is still applicable to pkgcheck and doesn't already exist.
