Maintain timestamps in yelp-build copied assets
This is maybe a bit esoteric, but it would be nice if yelp-build
would maintain timestamps for copied (rather than generated) assets. For example, any images copied for HTML output.
The use case I have is that we're uploading the generated docs to a web server (actually an AWS S3 bucket). Most reliable would be checking for updates by checksum, but it's faster to just check the date and size like rsync
does. At present, the fast path I have is just to check the size, which obviously isn't that reliable.
The fix would be simply `s/cp/cp --preserve=timestamps/'. What do you think?
