=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>] [I<upstream>]
=head1 DESCRIPTION
dh_installchangelogs is a debhelper program that is responsible for
installing changelogs into package build directories.
dh_installchangelogs determines if the package is a debian native package,
and if so, it installs debian/changelog into usr/share/doc/package/changelog
in the package build directory. Otherwise, it installs debian/changelog
into usr/share/doc/package/changelog.Debian in the package build directory. (If
files named debian/package.changelog exist, they will be used in preference
to debian/changelog.)
Parallelling the debian changelog handling, this program also takes care of
NEWS.Debian files. If there is a debian/NEWS file, it is installed as
usr/share/doc/package/NEWS.Debian. debian/package.NEWS files can also be
used.
If an upstream changelog file is specified as an option, then this upstream
changelog will be installed as usr/share/doc/package/changelog in the
package build directory. If the changelog is a html file (determined by
file extension), it will be installed as
usr/share/doc/package/changelog.html instead, and will be converted to
plain text with html2text to generate usr/share/doc/package/changelog.
=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 "changelog", and making a symlink from
that to the original name of the changelog file. This can be useful if the
upstream changelog has an unusual name, or if other documentation in the
package refers to the changelog file.
=item I<upstream>
Install this file as the upstream changelog.
