"""Copy the Breeze icons listed in misc/make_icon_themes.py into ico/breeze/.

Run from the repository root with a checkout of
https://github.com/KDE/breeze-icons:

    python3 misc/import_breeze_icons.py /path/to/breeze-icons
    python3 misc/make_icon_themes.py

For each Breeze name in BREEZE it writes the art Breeze draws at 16, 22
and 32 pixels, unchanged:

    ico/breeze/16/<name>.svg
    ico/breeze/22/<name>.svg
    ico/breeze/32/<name>.svg

Many Breeze names are symbolic links to another file. The copy holds the
linked file's content under the name BREEZE gives, so list the link's
target in BREEZE and several QET icons share one copy. Every name needs
22 pixel art; 16 and 32 are copied where Breeze has them.
