Hi
3) I can browse a Subversion repository with a web browser instead of having to download code from the repository from the command line (of course command line is still available). Sometimes viewing a version of a code sample online is all that is needed to answer a question, and in that case I prefer to look instead of downloading a file that I have to delete.
Darcs does have Darcsweb that can be used for the same purpose, with the full array of Darcs viewing features. Darcsweb isn't nearly as widespread as ViewCVS and the like, but it exists and can be set up easily enough.
http://darcs.haskell.org/darcsweb/darcsweb.cgi?r=yhc;a=summary - most things on haskell.org have a darcsweb, thats the one for Yhc. Plus I suspect that darcs will be discussed in the book, for building a library, in which case its only sensible to dogfood your own stuff. Not that darcs is dogfood, more like a chocolate cake :) Thanks Neil
