"""

Kallithea script for maintaining contributor lists from version control

history.

This script and the data in it is a best effort attempt at reverse engineering

previous attributions and correlate that with version control history while

preserving all existing copyright statements and attribution. This script is

processing and summarizing information found elsewhere - it is not by itself

making any claims. Comments in the script are an attempt at reverse engineering

possible explanations - they are not showing any intent or confirming it is

correct.

Three files are generated / modified by this script:

kallithea/templates/about.html claims to show copyright holders, and the GPL

license requires such existing "legal notices" to be preserved. We also try to

keep it updated with copyright holders, but do not claim it is a correct list.

CONTRIBUTORS has the purpose of giving credit where credit is due and list all

the contributor names in the source.

kallithea/templates/base/base.html contains the copyright years in the page

footer.

Both make a best effort of listing all copyright holders, but revision control

history might be a better and more definitive source.

Contributors are sorted "fairly" by copyright year and amount of

contribution.

New contributors are listed, without considering if the contribution contains

copyrightable work.

When the copyright might belong to a different legal entity than the

contributor, the legal entity is given credit too.
