<refsect1><title>Description</title>
<para>
  <command>gtk-update-icon-cache</command> creates mmapable cache
  files for icon themes.
</para>
<para>
  It expects to be given the <replaceable>PATH</replaceable> to a icon theme
  directory containing an <filename>index.theme</filename>, e.g.
  <filename>/usr/share/icons/hicolor</filename>, and writes a
  <filename>icon-theme.cache</filename> containing cached information about
  the icons in the directory tree below the given directory.
</para>
<para>
  GTK+ can use the cache files created by <command>gtk-update-icon-cache</command>
  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.
