+# - Functions to help assemble a standalone Qt4 application.
+# A collection of CMake utility functions useful for deploying
+# Qt4 applications.
+#
+# The following functions are provided by this module:
+#   fixup_qt4_bundle
+#   install_qt4_app
+# Requires CMake 2.6 or greater and depends on BundleUtilities.cmake.
+#
+#  FIXUP_QT4_BUNDLE(<app> <qtplugins> [<libs> <dirs>])
+# Copies Qt plugins, writes a Qt configuration file (if needed) and fixes up a
+# Qt4 executable using BundleUtilities.
+#
+#  INSTALL_QT4_APP(<executable> <qtplugins> [<libs> <dirs>])
+# Installs plugins, writes a Qt configuration file (if needed) and fixes up a
+# Qt4 executable using BundleUtilties.
