Advanced issues:

	* add autoconf/automake
	* support signed archives (how?)
	* move 90% of archzoom.cgi to some modules

Missing views:

	* history (log history with or without file constraint)
	* annotate (file annotation)
	* customize (to choose css, various view constants)

View improvements:

	* show file meta changes in file diff
	* show file meta changes in log? (tla does this in changeset, not log)
	* polish all templates
	* add configurable no-robots headers to pages
