fcgiwrap uses SCRIPT_FILENAME (if set) and the concatenation of
DOCUMENT_ROOT and SCRIPT_NAME otherwise.

Suggestions for the nginx config: generally a default, sane set of
fastcgi parameters is available in the fastcgi_params file which you can
include with "include fastcgi_params;".

For a working fcgiwrap + nginx config, see:
