Issue 5250 - Add copyright update script

update-copyright/README.md

+# update-copyright #

In general we don't add # at ends of headings in the markdown documents. It's
not a big deal to have them here, but I'd suggest to keep things consistent
unless there's a good reason to not do it.

Done.

+This script accepts a URL to a mercurial index as input. It then makes a local copy of each repo, updates the copyright information on every file to the current year, then attempts to push the updates. If a user doesn't have permission to push to a repo, the script will make a local `repo-name.patch` file to submit later. You are free to use it for other projects but please keep in mind that we make no stability guarantees whatsoever and might change functionality any time.

Another mostly consistency-related point: the long lines are usually wrapped to
80 characters elsewhere. There's no strong reason, but it's a bit easier to work
with shorter lines and any decent editor can do the wrapping automatically.

Done.

+## How to use ##
+
+To update the copyright on all the repos indexed at [https://hg.adblockplus.org/](https://hg.adblockplus.org/), you can use the accompanying shell script, e.g.:
+
+    ./run_update_copyright.sh
+
+To run the script elsewhere, you must specify the URL for a Mercurial index site to scrape, e.g.:
+
+    python3 update_copyright.py -u https://hg.example.com/
+
+You may also specify a base URL of a remote repo to push to, if it is different than the base URL of the index page, e.g.:
+
+    python3 update_copyright.py -u https://hg.example.com/ -p ssh://user@hg.example.com/
+
+## Testing ##

+Testing can be run via [tox](http://tox.readthedocs.org/).
