+=head1 SYNOPSIS
+
+B<dh_installdocs> [S<I<debhelper options>>] [B<-A>] [B<-X>I<item>] [S<I<file> ...>]
+
+=head1 DESCRIPTION
+
+B<dh_installdocs> is a debhelper program that is responsible for installing
+documentation into F<usr/share/doc/package> in package build directories.
+
+=head1 FILES
+
+=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>.
+
+=item F<debian/README.Debian>
+
+=item F<debian/TODO>
+
+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
+doc-base files, and can name them like this.
+
+=back
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-A>, B<--all>
+
+Install all files specified by command line parameters in ALL packages
+acted on.
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename from
+being installed. Note that this includes doc-base files.
+
+=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).
+
+=back
+
+=head1 EXAMPLES
+
+This is an example of a F<debian/package.docs> file:
+
+  README
+  TODO
+  debian/notes-for-maintainers.txt
+  docs/manual.txt
+  docs/manual.pdf
+  docs/manual-html/
+
+=head1 NOTES
+
+Note that B<dh_installdocs> will happily copy entire directory hierarchies if
+you ask it to (similar to B<cp -a>). If it is asked to install a
+directory, it will install the complete contents of the directory.
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
