Name
       gtk4-update-icon-cache - Icon theme caching utility

SYNOPSIS
       gtk4-update-icon-cache [OPTIONS...] 

DESCRIPTION
       gtk4-update-icon-cache creates mmap(2)-able cache files for icon themes.

       It  expects to be given the PATH to an icon theme directory containing an index.theme, e.g. /usr/share/icons/hicolor,
       and writes a icon-theme.cache containing cached information about the icons in the directory tree below the given di‐
       rectory.

       GTK can use the cache files created by gtk4-update-icon-cache to avoid a lot of system call and	disk  seek  overhead
       when  the application starts. Since the format of the cache files allows them to be shared across multiple processes,
       for instance using the POSIX mmap(2) system call, the overall memory consumption is reduced as well.

OPTIONS
       -f, --force
	  Overwrite an existing cache file even if it appears to be up-to-date.

       -t, --ignore-theme-index
	  Don't check for the existence of  index.theme	 in  the  icon	theme  directory.   Without  this  option,  gtk4-up‐
	  date-icon-cache  refuses to create an icon cache in a directory which does not appear to be the toplevel directory
	  of an icon theme.

       -i, --index-only
	  Don't include image data in the cache.

       --include-image-data
	  Include image data in the cache.

       -c, --source 
	  Output a C header file declaring a constant NAME with the contents of the icon cache.

       -q, --quiet
	  Turn off verbose output.

       -v, --validate
	  Validate existing icon cache.
