r"""
Script to delete files that are also present on Wikimedia Commons.
Do not run this script on Wikimedia Commons itself. It works based on
a given array of templates defined below.
Files are downloaded and compared. If the files match, it can be deleted on
the source wiki. If multiple versions of the file exist, the script will not
delete. If the SHA1 comparison is not equal, the script will not delete.
A sysop rights on the local wiki is required if you want all features of
this script to work properly.
This script understands various command-line arguments:
-always run automatically, do not ask any questions. All files
that qualify for deletion are deleted. Reduced screen
output.
-replace replace links if the files are equal and the file names
differ
-replacealways replace links if the files are equal and the file names
differ without asking for confirmation
-replaceloose Do loose replacements. This will replace all occurrences
of the name of the image (and not just explicit image
syntax). This should work to catch all instances of the
file, including where it is used as a template parameter
or in galleries. However, it can also make more mistakes.
-replaceonly Use this if you do not have a local sysop rights, but do
wish to replace links from the NowCommons template.
Example
-------
python pwb.py nowcommons -replaceonly -replaceloose -replacealways -replace
Todo
----
Please fix these if you are capable and motivated:
- if a file marked nowcommons is not present on Wikimedia Commons, the bot
will exit.
