=head1 SYNOPSIS
-B<dh_installdocs> [S<I<debhelper options>>] [B<-A>] [B<-X>I<item>] [S<I<file ...>>]
+B<dh_installdocs> [S<I<debhelper options>>] [B<-A>] [B<-X>I<item>] [S<I<file> ...>]
=head1 DESCRIPTION
-dh_installdocs is a debhelper program that is responsible for installing
-documentation into usr/share/doc/package in package build directories.
+B<dh_installdocs> is a debhelper program that is responsible for installing
+documentation into F<usr/share/doc/package> in package build directories.
-dh_installdocs automatically installs debian/copyright if it exists. If
-dh_installdocs is acting on multiple packages, debian/copyright files will be
-installed into all packages. However, if you need to have separate copyright
-files for different binary packages, you can use files named
-debian/package.copyright.
+=head1 FILES
-Any filenames specified as parameters will be installed into the first
-package dh_installdocs is told to act on. By default, this is the first
-binary package in debian/control, but if you use B<-p>, B<-i>, or B<-a> flags, it
-will be the first package specified by those flags.
+=over 4
+
+=item debian/I<package>.docs
+
+List documentation files to be installed into I<package>.
+
+=item F<debian/copyright>
+
+The copyright file is installed into all packages, unless a more
+specific copyright file is available.
+
+=item debian/I<package>.copyright
+
+=item debian/I<package>.README.Debian
+
+=item debian/I<package>.TODO
+
+Each of these files is automatically installed if present for a
+I<package>.
-Also, debian/README.Debian (or debian/README.debian) and debian/TODO, if
-they exist, will be installed into the first binary package listed in
-debian/control, if dh_installdocs is acting on that package. Note that
-debian/TODO will be installed named TODO.Debian, if the package is not a
-debian native package. Also note that README.debian is installed as
-README.Debian, for consistency. Note that debian/package.README.Debian and
-debian/package.TODO can be used to specify files for subpackages.
+=item F<debian/README.Debian>
-Files named debian/package.docs can list other files to be installed.
+=item F<debian/TODO>
-Files named debian/package.doc-base, will be installed as doc-base control
-files. Note that the doc-id will be determined from the "Document:" entry
-in the doc-base control file in question.
+These files are installed into the first binary package listed in
+debian/control.
+
+Note that F<README.debian> files are also installed as F<README.Debian>,
+and F<TODO> files will be installed as F<TODO.Debian> in non-native packages.
+
+=item debian/I<package>.doc-base
+
+Installed as doc-base control files. Note that the doc-id will be
+determined from the B<Document:> entry in the doc-base control file in
+question.
+
+=item debian/I<package>.doc-base.*
If your package needs to register more than one document, you need multiple
-files. To accomplish this, you can use files named debian/package.doc-base.*
+doc-base files, and can name them like this.

=head1 OPTIONS
Install all files specified by command line parameters in ALL packages
acted on.
-=item B<-Xitem>, B<--exclude=item>
+=item B<-X>I<item>, B<--exclude=>I<item>
-Exclude files that contain "item" anywhere in their filename from
+Exclude files that contain I<item> anywhere in their filename from
being installed. Note that this includes doc-base files.
-=item I<file ...>
+=item B<--link-doc=>I<package>
+
+Make the documentation directory of all packages acted on be a symlink to
+the documentation directory of I<package>. This has no effect when acting on
+I<package> itself, or if the documentation directory to be created already
+exists when B<dh_installdocs> is run. To comply with policy, I<package> must
+be a binary package that comes from the same source package.
+
+debhelper will try to avoid installing files into linked documentation
+directories that would cause conflicts with the linked package. The B<-A>
+option will have no effect on packages with linked documentation
+directories, and F<copyright>, F<changelog>, F<README.Debian>, and F<TODO> files will
+not be installed.
+
+(An older method to accomplish the same thing, which is still supported,
+is to make the documentation directory of a package be a dangling symlink,
+before calling B<dh_installdocs>.)
+
+=item I<file> ...
Install these files as documentation into the first package acted on. (Or
in all packages if B<-A> is specified).
