Redmine

I am using the documents tab of the project for delivering the outputs of my build to the customer.
Now I started to use the Jenkins CI server to do my builds for automatically.
And I would like to write a plugin to deploy the build output by Jenkins directly to the Redmine documents.
I was hanging around the Redmine sources looking for the REST API to be able to do this.
I either missed it (as I am not exactly good in Ruby, Rails and Redmine) or it is just not there.
If it is there then please accept my appologies for botherin here with it and just point me there.
Otherwise, please consider adding this REST API...

Thanks!
