The copy operation is intended to copy additional files into this target directory directory, merging the files copied from /mysrcdir/data with the files already present in /mydstdir. Beyond writing explicit Python code to do it, how can I get scons to not complain if the destination already when a Copy operation is done?


Use env.Install and env.Glob to find the files.
Don't copy directories as they automatically depend on their included files, but won't be updated if the directory content changes.
