It would be nice to enable a flag to make possible comparing a given original language with many others. It'd be something like:

 if (flag){
    folders := lookup(GivenRootFolderOfFolders)
    for _, f := range folders {
        compare(english,join(GivenRootFolderOfFolders,'/',f))
    }
}

This will enable contribution to N repositories with a single command.
