Each directory is scanned for font files readable by FreeType. A cache is created\nwhich contains properties of each font and the associated filename.  This cache  is  used  to\nspeed up application startup when using the fontconfig library.\n\nNote  that  fc-cache must be executed once per architecture to generate font information cus‐\ntomized for that architecture.\n",
