He also wrote a demo application in Visual Basic for editing a Manila site's home page. I wanted to take some time here to explain what this is, and why it's important. First, a little background. Manila is a web service . Human beings edit their Manila web sites using pages their web browser, which collectively make up Manila's user interface.
Manila also has an interface which programs can use to manipulate web sites.
The RPC interface is a collection of functions for performing specific actions on your Manila website. To do this, I open the site up in my web browser, and log in. Then I scroll to the bottom of my home page, and click the Edit This Page button. A new page loads, with a form for editing the text on my home page. Using Manila's RPC interface, a program can do the same thing.
