I was reading “Good project- and archive- naming practice”](http://en.tldp.org/HOWTO/Software-Release-Practice-HOWTO/naming.html#AEN142), and the use of major.minor.patch numbering.
I often see additional numbers after the patch, for example only, “gimp-2.4.6-1.3.i586.rpm”. Sometimes those numbers after the patch ("-1.3") are the only thing that is different in multiple entries in the search results. I know what the “gimp-2.4.6” means. I know what the “i586.rpm” means, but what does the “-1.3” mean? If it isn’t a new release, a minor update or a patch, what is it?
When looking at SuSE repositories, what is the significance of a directory with and without a colon, like MONO/ and MONO:/, PRINTING/ and PRINTING:/ or SUSE:/, etc?
