 # Will create 'shatter.dat' in the respective binary directory containing all files in 'shatter' subdirectory of current

-# To create the archive Datafile.exe is used, so for non-Windows platforms an emulator that can run it is needed.
+# Optionally, RESOURCES can be used to specify binary resource targets from AddDownloadableResource that will provide
