<refsect1><title>Description</title>
<para><command>gtk-update-icon-cache</command> creates mmap()able cache files for
icon themes. 
</para>
<para>
It expects to be given the path 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 mmap()ed shared between
multiple applications, the overall memory consumption is reduced as well.
