2# Fonts shipped with the SDK need to be renamed for Java to handle them
3# properly. Hence, a special script is used to rename the fonts. We bundle all
4# the fonts that are shipped on a newer non-space-constrained device. However,
5# OpenType fonts used on these devices are not supported by Java. Their
6# replacements are added separately.
