@enumerate
@item Distributed: Every user has access to the full command set, removing boundaries
between server and client or committer and non-committers.
@item Interactive: Darcs is easy to learn and efficient to use because it asks you
questions in response to simple commands, giving you choices in your work flow.
You can choose to record one change in a file, while ignoring another.  As you update
from upstream, you can review each patch name, even the full diff for interesting
patches.
@item Smart: Originally developed by physicist David Roundy, darcs is based on a
unique algebra of patches called @url{http://darcs.net/Theory,Patchtheory}.
