In the fourth bullet in the list the phrase deal.II is a bit unclear to me. Is it meant to be the name of some generic project? If so, I think the meaning would be conveyed more clearly by just saying "some project" or something similar.
I had written this text originally as an aid for the developers of the deal.II project (my own open source project) and then copied it to the KDevelop manual. I meant to purge all references to deal.II from the text I copied, but apparently forgot this one. I've removed it now.
