Converting XCF and other files using command line with GIMP?

Question

If I have an XCF file (or any other supported by Gimp) how can I convert it to, for example, PNG for display or further processing?

Answer 1

A very good solution (and explanations!) can be found here. In short, there is a bash script feeding scheme/lisp to gimp

#!/bin/bash
{
cat <
