Yep, it's the shell script version I'm still using at university, too.

Agreed. It's not event released and already many users complained. I was
bitten by it myself when changing from the shell version to Frank's texlua
version.

In r10073:

        viewer_pdf  = os.getenv ("PDFVIEWER")
        or os.getenv ("TEXDOCVIEW_pdf") or os.getenv ("TEXDOC_VIEWER_PDF"),

and so on. I preferred giving precedence to the new names.

The more elaborate thing is the set_config_list which eats the above list, and
takes care of merging it with what comes from the config files (envvar have
precedence). You can set the viewers in texdoc.cnf, not in texmf.cnf, since I
think it's not a very good place for user's personal settings.
