+=head1 DESCRIPTION
+
+dh_installchangelogs is a debhelper program that is responsible for
+installing changelogs into package build directories.
+
+An upstream changelog file may be specified as an option. If none is
+specified, a few common filenames are tried. (In compatibility level 7 and
+above.)
+
+If there is an upstream changelog file, it will be 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.

+
+Automatically installed into usr/share/doc/I<package>/
+in the package build directory.
+
+Use the package specific name if I<package> needs a different
+NEWS or changelog file.
+
+The changelog file is installed with a name of changelog
+for native packages, and changelog.Debian for non-native packages.
+The NEWS file is always installed with a name of NEWS.Debian.

+=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 B<-Xitem>, B<--exclude=item>
+
+Exclude upstream changelog files that contain "item" anywhere in their
+filename from being installed.
+
+=item I<upstream>
+
+Install this file as the upstream changelog.
