1. Count and list the pages containing Wikipedia articles for deletion discussions (AfD).
2. Archive the pages on which all deletion discussions are closed.
3. Initialize pages for the upcoming days.

1. Discussions more than this number of days in the past are considered old and must be listed at AfD

1. This line must be the first to print in a cgi script

print "Content-type: text/html\n\n";

print "Please be patient, this script can take a minute or two " . "if Wikipedia is slow ...

\n";

2. script from crontab), go to that directory first

my $cur_dir = $0; # $0 stands for the executable, with or without full path if ($cur_dir =~ /^\//){ $cur_dir =~ s/^(.*)\/.*?$/$1/g; chdir $cur_dir; }else{ }

1. Display the number of open afd discussions in the pages listed in
2. in $summary_file and put links to those those discussions in $detailed_file.
3. Return the list of pages in $combined_stats, we'll need that to decide which
4. pages to archive.

my $combined_stats = &count_and_list_open_AfDs($summary_file, $detailed_file, $attempts, $sleep);

2. which is the text in $combined_stats

my $archive_file = "Wikipedia:Archived deletion discussions.wiki"; &update_archived_discussions($archive_file, $combined_stats, $attempts, $sleep);

1. Find the number of open discussions for each listed day

1. extract the links to the open discussions

1. Any day in the current year up no earlier than
2. $afd_cutoff+2 days ago is a candidate to be in the archive
