# As an optimisation, --http can be replaced with --socket; if we update nginx
# settings to use uwsgi_pass instead of proxy_pass.

# --log-maxsize enables log rotation --- unless specified otherwise, current
# --log file is moved to file with Unix timestamp as suffix.  To limit the
# --number of files/the disk space utilisation, we specify --log-backupname,
# --with the single file name to be overwritten on rotation.

# --log-x-forwarded-for logs X-Forwarded-For rather than REMOTE_ADDR --- so the
# --address of the client, as specified by nginx, rather than the address of
# --the local nginx.

# --stats lets us fetch server status/stats at the specified address --- which
# --might e.g. be monitored with uwsgitop.  (JSON status dump on TCP
# --connection.)
