+# osu! Emoji Generator Script
+# ==============================================================================
+# This script generates emoji images for use with osu!, based on emoji from 
+# the Google Noto Color Emoji project: https://github.com/googlefonts/noto-emoji
+#
+# REQUIREMENTS:
+# - This script should be copied into the root directory of the noto-emoji 
+#   repository after cloning
+# - vips image processing library from https://www.libvips.org/install.html
+#   is required to run this script
+#
+# OUTPUT:
+# - Generates an Emoji.zip file containing emoji images
+# - Each emoji image is 50x50 pixels, stored as raw RGBA32 image data
+# - Image filename format: emoji unicode hex sequence with _ as separator
+#
+# EXAMPLES:
+# - "👍" (U+1F44D) -> "1f44d.raw"
+# - "👨‍👩‍👧‍👦" (U+1F468 U+200D U+1F469 U+200D U+1F467 U+200D U+1F466) -> "1f468_200d_1f469_200d_1f467_200d_1f466.raw"
