Copying directories as resources

When Xcode copies directories in a resources build phase, it leaves so 
all kinds of stuff you normaly don't want (such as version control 
info, .DS_STORE, etc). However I could not find a tool that can do 
this in an easy way. Is this tool somehow publicly available on the 
system, so I can use it in a custom script build phase?

thanks,
