+# This is a very basic file for the new style find_package() search mode,
+# i.e. Config-mode.
+# In this mode find_package() searches for a <package>Config.cmake
+# file and an associated <package>Version.cmake file, which it loads to check
+# the version number.
+# This file can be used with configure_file() to generate such a file for a project
+# with very basic logic.
+# It sets PACKAGE_VERSION_EXACT if the current version string and the requested
+# version string are exactly the same and it sets PACKAGE_VERSION_COMPATIBLE
+# if the current version is >= requested version.
+# If this is not good enough for your project, you need to write your own
+# improved <package>Version.cmake file.
