+# TODO: Update to match new AddDownloadableResource.
 # Adds a target that creates a datafile archive containing all files under selected directory tree. For example:
 #
 #     add_datafile(
 #         shatter
-#         DIRECTORY shatter
+#         SOURCE shatter
 #         OUTPUT shatter.dat
 #     )
 #
 # Will create 'shatter.dat' in the respective binary directory containing all files in 'shatter' subdirectory of current
-# source directory. DIRECTORY option's argument defaults to the target name. OUTPUT option's argument defaults to the
+# source directory. SOURCE option's argument defaults to the target name. OUTPUT option's argument defaults to the
 # target name with ".dat" suffix.
 #
 # To create the archive Datafile.exe is used, so for non-Windows platforms an emulator that can run it is needed.
