+#   run_test(description, script) - run one test, i.e. eval script

+# Helper functions
+#   cgit_query(querystring) - call cgit with the specified querystring
+#   cgit_url(url) - call cgit with the specified virtual url

+# run_test 'repo index' 'cgit_url "/" | tidy -e'
+# run_test 'repo summary' 'cgit_url "/foo" | tidy -e'
