We go one step further than that - we have a working copy on the web
server that is updated by a hook script whenever something is checked
in, and a 'make' is run in it (to do xslt transforms to create the
static web pages). The output files from that transform are visible as
a 'staging' server, and then a cgi on the main site uses rsync to move
any changed files to the real web site.

Each step only touches files that have actually changed, and all
dependencies are accounted for.
