Setting SPF record on Amazon Route 53 with cli53 tool

Question

My domain is already with Amazon Route 53 and I can use the cli53 command line tool quite happily to maintain it.

We are moving to use Amazon SES and I would like to add an SPF record to the domain, as per the docs... we have no prior existing record. This is just for automated emails to customers, not internal user accounts.

I can't for the life of me figure out what the command line is to do this, can anyone provide an example?

$ cli53 rrcreate -x 3600 -r --wait mydomain.com '' 'SPF' 'v=spf1 include:amazonses.com ?all'
