when $0 isn't what I want

[Chad Perrin]

When using eruby for web development, $0 for any given .rhtml file is
always 'eruby'. This also means that any time I want to use a path
relative to the location of the .rhtml file being accessed, I'm out of
luck: paths are relative to the eruby executable instead.

How would I go about using relative paths from a current working path of
the .rhtml file, rather than from the eruby executable? I'd prefer a
more "portable" design for the code in the pages I'm putting together,
rather than having to use absolute paths that may lose their accuracy if
the web pages in question ever need to be moved to another server.

File.dirname(__FILE__)

Variations with Pathname are much more programmer-friendly, too!

I coulda sworn I'd tried that already. Apparently not.

Thanks!
