+SUMMARY="A free assembler/linker package for the Game Boy and Game Boy Color"
+DESCRIPTION="RGBDS' four programs cover the whole compilation pipeline into a \
+ready-to-play ROM, from RGBGFX (the image converter) to RGBFIX (the header \
+\"fixer\").
+Each tool can easily be swapped for a custom one, or used stand-alone as part \
+of another process."
