=head1 NAME

dh_installxmlcatalogs - install and register XML catalog files

=head1 SYNOPSIS

B<dh_installxmlcatalogs> [S<I<debhelper options>>] [B<-n>]

=head1 DESCRIPTION

B<dh_installxmlcatalogs> is a debhelper program that installs and
registers XML catalog files.  It complies with the Debian XML/SGML
policy.

The file F<debian/I<package>.xmlcatalogs> lists the local XML catalog
files to be installed per package as well as the XML entities in those
local XML catalog files that are to be registered in the XML catalog
system.

The local XML catalog file entries in that file should be of the form
C<local;source;dest>, where the verbatim C<local> indicates this is an
entry for a local XML catalog file, C<source> indicates where the
local XML catalog resides in the source tree, and C<dest> indicates
the destination location for the local XML catalog under the package
build area.  C<dest> should start with F</usr/share/xml/>.

The entries for the XML entities to be registered in the package XML
catalog file should be of the form C<package;type;id;catalog>, where
the verbatim C<package> indicates this is an entry for an XML entity
to be registered in the package XML catalog file, C<type> indicates
the XML entity type (public, system, uri), C<id> indicates the XML
entity id, and C<catalog> indicates the local XML catalog file.

The entries for the XML entities to be registered in the root XML
catalog file should be of the form C<root;type;id>, where the verbatim
C<root> indicates this is an entry for an XML entity to be registered
in the root XML catalog file, C<type> indicates the XML entity type
(public, system, uri), and C<id> indicates the XML entity id.

If an entry for is to be registered identically in the root catalog
and the package catalog file, you can use the form
C<root-and-package;type;id;catalog>, where the verbatim
C<root-and-package> indicates this is an entry for an XML entity to be
registered in both the root and package XML catalog files, C<type>
indicates the XML entity type (public, system, uri), C<id> indicates
the XML entity id, and C<catalog> indicates the local XML catalog
file.

XML entity types are described in L<update-xmlcatalog(8)>.  Using the
C<root> or C<package> commands, a type of C<public> will general
C<delegatePublic> statements in the applicable catalog file. Generally
you will want to use the types C<public> for any formal public
identifiers, and C<system> for any files on the local filesystem or
URLs.  C<uri> is only used for non-local files which are not part of
the external document subset, e.g., they are not used for entities or
DTDs.

B<dh_installxmlcatalogs> automatically adds maintainer script snippets
for the registration and unregistration of the listed XML entities in
the XML catalog system (unless B<-n> is used).	A dependency on the
B<xml-core> package will be added to C<${misc:Depends}>, so be sure to
use that variable in the file F<debian/control>.  See
L<dh_installdeb(1)> for an explanation of Debhelper maintainer script
snippets.

Note that this command is not idempotent. "dh_clean -k" should be
called between invocations of this command. Otherwise, it may cause
multiple instances of the same text to be added to maintainer scripts.
