2.3. Defining Variables

Our current use of tpage for processing templates is hardly streamlined. We're spending a lot of time typing variable values on the command line, something that can only get worse as we add more pages that require processing to the site.

It would be easy to mistype the value for a variable, for example, or perhaps supply the wrong value altogether. You wouldn't see any complaint from the Template Toolkit. It would just go right ahead and process the template with whatever values you supplied, possibly leading to an error on an HTML page that could go unnoticed.
