--- Comment #6 from Zbigniew Jędrzejewski-Szmek zbyszek@in.waw.pl --- There's no hard rule. For documentation, it's suggested to split it out if it's more than a megabyte or so. For shared data, if it's a few megabytes... It mostly saves some space on mirrors. Another minor advantage is that most likely the data doesn't change much, so drpm will save most of the download.
