Also keep in mind older checkouts use existing sample files, that means in
practice generally do not replace, remove or overwrite files as it likely would
break older checkouts or releases.
+Also all needed samples for a commit should be uploaded, ideally 24
+hours, before the push.
@example
#First update your local samples copy:
Specify which hardware acceleration to use while running regression tests,
by default @samp{none} is used.
+@item KEEP
+Set to @samp{1} to keep temp files generated by fate test(s) when test is successful.
+Default is @samp{0}, which removes these files. Files are always kept when a test
+fails.
