"""Build static/icons.svg: one SVG sprite with every glyph the game uses.
|
||
|
|
|
||
|
|
The glyphs are from game-icons.net (CC BY 3.0, see README), fetched through
|
||
|
|
the Iconify API. Run this after adding a glyph name in game.py; the sprite is
|
||
|
|
committed, so the game itself never fetches anything at runtime.
