43This script will clean up the category table by removing entries
for empty
44categories without a description page and adding entries
for empty categories
45with a description page. It will print out progress indicators every batch. The
46script is perfectly safe to
run on large, live wikis, and running it multiple
47times is harmless. You may want to use the throttling options
if it
's causing
48too much load; they will not affect correctness.
50If the script is stopped and later resumed, you can use the --mode and --begin
51options with the last printed progress indicator to pick up where you left off.
53When the script has finished, it will make a note of this in the database, and
54will not run again without the --force option.
