	## adjust config.h:
	cp -a config.h config.h.org
	## sed-bits: (some of this need a local USE-FLAG)
	##	1. set php-interpreter to use.
	##	2. prevent serving of cgis (files with exec-bit have to be cgis!).
	##	3. supress our version -- only say we are "thttpd" (paranoia-setting).
	##	4. user-homes live in webroot -- so we can chroot() the server.
	##	5. running CGIs under the owner's uid prevents running thttpd as non-root.
	## TODO:
	##	- syslog: errors to syslog instead of stderr.
	##	- stats-reporting: once a day instead of once per hour.
	##	- auth-file handling: recurse, use-global, ... ?
	##	- handlers: remove all, completely custom, ... ?
	##	... chroot, vhost (vhost-dirlevels), default-user, indexes, ... (more?)
