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.
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 -p, -i, or -a flags, it will be the first package specified by those flags.
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.
Files named debian/package.docs can list other files to be installed.
Files named debian/package.doc-base, will be installed as doc-base control files, and will make this program automatically generate the postinst and prerm commands needed to interface with the doc-base package. Note that the doc-id will be determined from the ``Document:'' entry in the doc-base control file in question.

Note that this command is not idempotent. "dh_clean -k" should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to maintainer scripts.
