<title>DESCRIPTION</title>
<para>
&xmlcatalog; is a command line application allowing users to monitor and
manipulate <acronym>XML</acronym> and <acronym>SGML</acronym> catalogs. It
is included in <citerefentry>
<refentrytitle>libxml</refentrytitle>
<manvolnum>3</manvolnum>
</citerefentry>.
</para>
<para>
Its functions can be invoked from a single command from the command line,
or it can perform multiple functions in interactive mode. It can operate
on both <acronym>XML</acronym> and <acronym>SGML</acronym> files.
</para>
</refsect1>
<refsect1 id="options">
<title>OPTIONS</title>
<para>
&xmlcatalog; accepts the following options (in alphabetical order):
</para>
<variablelist>
<varlistentry>
<term>
<option>--add
<replaceable>TYPE</replaceable>
<replaceable>ORIG</replaceable>
<replaceable>REPLACE</replaceable>
</option>
</term>
<listitem>
<para>
Add an entry to <filename>CATALOGFILE</filename>. <replaceable>TYPE</replaceable>
indicates the type of entry. Possible types are: <simplelist type="inline">
<member><parameter>public</parameter></member>
<member><parameter>system</parameter></member>
<member><parameter>uri</parameter></member>
<member><parameter>rewriteSystem</parameter></member>
<member><parameter>rewriteURI</parameter></member>
<member><parameter>delegatePublic</parameter></member>
<member><parameter>delegateSystem</parameter></member>
<member><parameter>delegateURI</parameter></member>
<member><parameter>nextCatalog</parameter></member>
</simplelist>. <replaceable>ORIG</replaceable> is the original
reference to be replaced, and <replaceable>REPLACE</replaceable>
is the <acronym>URI</acronym> of the replacement entity to be
used. The <option>--add</option> option will not overwrite
<filename>CATALOGFILE</filename>, outputting
to <filename class="devicefile">stdout</filename>, unless
<option>--noout</option> is used. The <option>--add</option> will
always take three parameters even if some of the <acronym>XML</acronym>
catalog constructs will have only a single argument.
</para>
<!--
FIXME - Is my list of possible types correct? Are SGML types the same?
-->
</listitem>
</varlistentry>
<varlistentry>
<term><option>--add <replaceable>FILENAME</replaceable></option></term>
<listitem>
<para>
If the <option>--add</option> option is used following
the <option>--sgml</option> option, only a single argument,
a <replaceable>FILENAME</replaceable>, is used. This is used to add
the name of a catalog file to an <acronym>SGML</acronym> supercatalog,
a file that contains references to other included <acronym>SGML</acronym>
catalog files.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--create</option></term>
<listitem>
<para>
Create a new <acronym>XML</acronym> catalog. Outputs
to <filename class="devicefile">stdout</filename>,
ignoring <replaceable>filename</replaceable> unless <option>--noout</option> is
used, in which case it creates a new catalog
file <replaceable>filename</replaceable>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--del <replaceable>VALUE(S)</replaceable></option></term>
<listitem>
<para>
Remove entries from <replaceable>CATALOGFILE</replaceable>
matching <replaceable>VALUE(S)</replaceable>. The <option>--del</option>
option will not overwrite <replaceable>CATALOGFILE</replaceable>,
outputting to <filename class="devicefile">stdout</filename>,
unless <option>--noout</option> is used.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--noout</option></term>

Save output to the named file rather than outputting

<title>SHELL COMMANDS</title>
<para>
Invoking &xmlcatalog; with
the <option>--shell <replaceable>CATALOGFILE</replaceable></option> option opens

provides a command line prompt after which the following commands (described in
alphabetical order) can be entered.
