 481 will store the same representation in a Git repository, bridged over arbitrary

 630 handling of command-line flags in Bourne based Unix shell scripts (bash, dash,
 631 ksh, sh, zsh).  Most shell scripts use getopt for flags processing, but the
 632 different versions of getopt on various OSes make writing portable shell
 633 scripts difficult.  shFlags instead provides an API that doesn't change across
 634 shell and OS versions so the script writer can be confident that the script

1620 @enumerate
1621 @item Distributed: Every user has access to the full command set, removing boundaries
1622 between server and client or committer and non-committers.
1623 @item Interactive: Darcs is easy to learn and efficient to use because it asks you
1624 questions in response to simple commands, giving you choices in your work flow.
1625 You can choose to record one change in a file, while ignoring another.  As you update
1626 from upstream, you can review each patch name, even the full diff for interesting
1627 patches.
1628 @item Smart: Originally developed by physicist David Roundy, darcs is based on a
1629 unique algebra of patches called @url{http://darcs.net/Theory,Patchtheory}.
