Then, when Ghostscript needs to find a font that isn’t already loaded into memory, it goes through a series of steps.
Therefore GenericResourceDir may be considered as a place where new resources to be installed. The build system will cope with the file being removed, and the initialization code will avoid adding the internal fall back mapping if the file is missing.
