+  The ``PACKAGE_INFO`` form generates and installs a |CPS| file which describes
+  installed targets such that they can be consumed by another project.
+  Target installations are associated with the export ``<export-name>``
+  using the ``EXPORT`` option of the :command:`install(TARGETS)` signature
+  documented above.  Unlike :command:`install(EXPORT)`, this information is not
+  expressed in CMake code, and can be consumed by tools other than CMake.  When
+  imported into another CMake project, the imported targets will be prefixed
+  with ``<package-name>::``.  By default, the generated file will be called
+  ``<package-name>[-<appendix-name>].cps``.  If ``LOWER_CASE_FILE`` is given,
+  the package name as it appears on disk (in both the file name and install
+  destination) will be first converted to lower case.
+
+  If ``DESTINATION`` is not specified, a platform-specific default is used.
+
+  If ``APPENDIX`` is specified, rather than generating a top level package
+  specification, the specified targets will be exported as an appendix to the
+  named package.  Appendices may be used to separate less commonly used targets
+  (along with their external dependencies) from the rest of a package.  This
+  enables consumers to ignore transitive dependencies for targets that they
+  don't use, and also allows a single logical "package" to be composed of
+  artifacts produced by multiple build trees.
+
+  Appendices are not permitted to change basic package metadata; therefore,
+  none of ``VERSION``, ``COMPAT_VERSION``, ``VERSION_SCHEMA``,
+  ``DEFAULT_TARGETS`` or ``DEFAULT_CONFIGURATIONS`` may be specified in
+  combination with ``APPENDIX``.  Additionally, it is strongly recommended that
+  use of ``LOWER_CASE_FILE`` should be consistent between the main package and
+  any appendices.
