xorg-x11-fonts-update-dirs [--skip-fontscale] [--need-ttmkfdir] path

The xorg-x11-fonts-* rpm packages call xorg-x11-fonts-update-dirs during %post and %postun to update the X11 font indices. This script may change in incompatible ways without notice and  you should not run this script manually or rely on it otherwise. To manually update the font indices invoke mkfontscale and ttmkfdir directly as required.
