<title>Description</title>
<para>
<link linkend="gnome-url-show">gnome_url_show</link>() provides a simple way to display information to the
user.  <link linkend="gnome-url-show">gnome_url_show</link>() knows about the <type>man:</type>,
<type>info:</type> and <type>ghelp:</type> special URL prefixes and
will invoke the proper display program for those. </para>

<para>
Any other URL is passed to the default information display handler
(usually this defaults to the <filename>gnome-moz-remote</filename>
program (which uses Mozilla to display the URL). </para>

<para><link linkend="gnome-url-show">gnome_url_show</link>() uses the user configured programs for the
different URL types.  The settings for each one of these handlers is
stored in the configuration file <filename>~/.gnome/Gnome</filename>
in the section "URL Handlers".  The possible keys are:</para>

    <para><emphasis>info-show:</emphasis> The command to display an
    <type>info:</type> URL.</para></listitem>

  <listitem>
    <para><emphasis>man-show:</emphasis> The command to display an
    <type>man:</type> URL.</para></listitem>

  <listitem>
    <para><emphasis>ghelp-show:</emphasis> The command to display an
    <type>ghelp:</type> URL (this is a GNOME-relative help
    document).</para></listitem>

  <listitem>
    <para><emphasis>default-show:</emphasis> The command to display
    any URL type which is not covered by the other cases.</para></listitem>

</itemizedlist>

<para>The command specification should include a
<filename><literal>s</literal></filename> specification.  The <filename><literal>s</literal></filename>
will be substituted with the URL thas was passed to the gnome_url_show
function.</para>

<programlisting>void        gnome_url_show                  (const char *url);</programlisting>
<para>
Loads the given URL in an appropriate viewer.  The viewer is deduced from
the protocol part of the URL.  That is all that the caller should know
about the function.
</para>
<para>
Internally, the handler for a given URL is deduced by looking in the
/Gnome/URL Handlers/&lt;protocol&gt;-show key in the user's configuration
files.  The key is a string that will be passed to <link linkend="gnome-execute-shell">gnome_execute_shell</link>(),
after the <literal>s</literal> is replaced with with the URL.  If that key can't be found,
it falls back to /Gnome/URL Handlers/default-show, and if that isn't
found, uses the contents of the DEFAULT_HANDLER macro in this file.
</para>
<para>
If no /Gnome/URL Handlers keys are set, some sensible defaults are added
to the user's configuration files.
</para>
<para>
We really need a capplet so a user can configure the behaviour of this
function.</para>
