I just found last week that the POD for my Audio::Beep module has been translated into Japanese by the perldoc.jp project. So I offered them to include their translation into my CPAN release of the module. Now for a few questions:

• What's the best place to install the Japanese documentation? My first thought was to install it as Audio::Beep_jp, but i'm not sure that's correct.
• Would it be acceptable to render Makefile.PL interactive and ask which version of the documentation to install? Could it broke non-interactive installations by CPAN Testers?
• What about checking some locale variable to automatically make a choice? But my guess is it could be error prone, so i'm not sure.

Maybe something coded along the lines of the following pseudo-code could do the trick:

if (shell is interactive) {
    if (ask "Do you want to install Japanese docs?") {
        install japanese_docs;
    } else {
        install standard_docs;
    }
} else {
    if (check_locale == 'jp') {
        install japanese_docs;
    } else {
        install standard_docs;
    }
}

What you think? Any better ideas or any guidelines or already defined standards? Thanks.
