How can I create a PgAgent job creation script?

I am preparing an installation disk for a customer. Their installation
includes over ten scheduled jobs. The only way I know of to create a
job is through PGAdmin, using a wizard to enter each piece of
information one screen at a time. I don't want to have to prepare an
instruction document that lists each individual step for creating each
of ten jobs. Is there a way to generate a set of SQL statements for an
existing job as we can for tables, so that all I have to tell the
customer to do is to run a batch file of psql calls to create the jobs?

Thank you very much.
