The answer said --region us keeps only your region's BIOS, with nothing
to run. On the PlayStation it keeps 44 files, Japanese PS2 images among

The site test modules were cut by review pass (test_site_r2_css to test_site_r5_wiki): the passes of one subject become one module, and the modules that stood alone take the name of what they hold. The installer test classes named after a review take the name of what they test. One test left --manifest set for the tests after it, which the new order showed: it now resets the sources.
