+/* test_xml.js
+ * This file sets up the unit test environment by building an array of files
+ * to be tested. It assumes it lives in a folder adjacent to the a folder
+ * called 'xml', where the testcases live.
+ *
+ * The directory layout looks something like this:
+ *
+ * tests/test_xml.js*
+ *      |
+ *      - head.js
+ *      |
+ *      - xml/ -- rss1/...
+ *             |
+ *             -- rss2/...
+ *             |
+ *             -- atom/testcase.xml
+ *
+ * To add more tests, just include the file in the xml subfolder and add its name to xpcshell.ini
