=head1 NAME
dh_installchangelogs - install changelogs into package build directories
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installchangelogs> [S<I<debhelper options>>] [B<-k>] [B<-X>I<item>] [I<upstream>]
=head1 DESCRIPTION
B<dh_installchangelogs> is a debhelper program that is responsible for
installing changelogs into package build directories.
An upstream F<changelog> file may be specified as an option. If none is
specified, it looks for files with names that seem likely to be changelogs.
(In compatibility level 7 and above.)
If there is an upstream F<changelog> file, it will be be installed as
F<usr/share/doc/package/changelog> in the package build directory. If the
changelog is a F<html> file (determined by file extension), it will be
installed as F<usr/share/doc/package/changelog.html> instead, and will be
converted to plain text with B<html2text> to generate
F<usr/share/doc/package/changelog>.
=head1 FILES
=over 4
=item F<debian/changelog>
=item F<debian/NEWS>
=item debian/I<package>.changelog
=item debian/I<package>.NEWS
Automatically installed into usr/share/doc/I<package>/
in the package build directory.
Use the package specific name if I<package> needs a different
F<NEWS> or F<changelog> file.
The F<changelog> file is installed with a name of changelog
for native packages, and F<changelog.Debian> for non-native packages.
The F<NEWS> file is always installed with a name of F<NEWS.Debian>.
=back
=head1 OPTIONS
=over 4
=item B<-k>, B<--keep>
Keep the original name of the upstream changelog. This will be accomplished
by installing the upstream changelog as F<changelog>, and making a symlink from
that to the original name of the F<changelog> file. This can be useful if the
upstream changelog has an unusual name, or if other documentation in the
package refers to the F<changelog> file.
=item B<-X>I<item>, B<--exclude=>I<item>
Exclude upstream F<changelog> files that contain I<item> anywhere in their
filename from being installed.
=item I<upstream>
Install this file as the upstream changelog.
