## NAME
       gtk-update-icon-cache - Icon theme caching utility

## SYNOPSIS
       **gtk-update-icon-cache** [--force] [--ignore-theme-index] [--index-only | --include-image-data]
                             [--source _NAME_] [--quiet] [--validate] _PATH_

## DESCRIPTION
       **gtk-update-icon-cache** creates mmapable cache files for icon themes.

       It expects to be given the _PATH_ to a 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 **gtk-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 mmaped shared between multiple applications, the overall memory consumption
       is reduced as well.

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

### --ignore-theme-index, -t
           Don't check for the existence of index.theme in the icon theme directory. Without this
           option, **gtk-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.

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

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

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

### --quiet, -q
           Turn off verbose output.

### --validate, -v
           Validate existing icon cache.
