+"""Delink removed files from wiki.
+
+This script keeps track of image deletions and delinks removed files
+from current wiki in namespace 0. This script is suitable to delink
+files from a image repository as well as for local images.
+
+The following parameters are supported:
+
+-exclude: If the deletion log contains this pattern, the file is not
+ delinked (default is 'no-delink').
+
+-localonly Retrieve deleted File pages from local log only
+
+-since: Start the deletion log with this timestamp given in MediaWiki
+ timestamp format. If no `-since` option is given, the start
+ timestamp is read from setting file. If the option is empty,
+ the processing starts from the very beginning. If the script
+ stops, the last timestamp is written to the settings file and
+ the next script call starts there if no `-since` is given.
+
+.. note:: This sample script is a
+ :class:`ConfigParserBot <pywikibot.bot.ConfigParserBot>`. All
+ settings can be made either by giving option with the command line or
+ with a settings file which is scripts.ini by default. If you don't
+ want the default values you can add any option you want to change to
+ that settings file below the [delinker] section like.
+
+.. versionadded:: 7.2
+ This script is completely rewriten from compat branch.
