Well, that's good news, Mike, but what about the following did I not
understand?  When you said =22isn't stored usually=22, I guess you meant
that, if there a file is used, it is.

This would be nice to have in the docs.

Thanks.

That's not accurate. Of course it's kept, otherwise the file appender
wouldn't know what the name of the file is, right? :)

To find the name of the file the file appender is using, first obtain a
reference to the file appender. If you have a configuration like

    log4perl.category.Bar.Twix         =3D WARN, Logfile
    log4perl.appender.Logfile          =3D Log::Log4perl::Appender::File
    log4perl.appender.Logfile.filename =3D test.log
    ...

then find the =22Logfile=22 appender via

    my =24app =3D Log::Log4perl->appender_by_name(=22Logfile=22);

and to obtain the name of the logfile it's using, call its 'filename'
method:

    print =24app->filename(), =22=5Cn=22;
