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

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 directory.

       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.

-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-update-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<NAME>
          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.
