recognizing a job on Ubuntu 8.04.1

I'm having trouble getting upstart to recognize a job I've created. I'm trying to set up a sobby server. I placed the following script in /etc/init/jobs.d (a directory I had to create):

-------------------------8<-------------------------
# sobby

description "dedicated server for collaborative editing"

/usr/bin/sobby --autosave-file=/var/lib/sobby/autosave /var/lib/sobby/autosave
------------------------->8-------------------------

But start/stop/status don't seem to work:

$ sudo status sobby
status: Unknown job: sobby

I'm basically following directions posted here: http://upstart.ubuntu.com/getting-started.html

Any ideas?
