The tags are shorthand for the license of each file and avoid
copying the full license text into each one (and avoids having
to manually update the dates in each one...).
Python 3 makes a number of changes to the language and breaks backward
compatibility with Python 2 in some places. This change updates the
Python scripts used in the build system to work with Python 3,
although the updated scripts still run in Python 2 as well. Most of
the changes are minor; the biggest changes are to the palette /
colormap generation scripts.
