The default document-root (if unspecified) is the system root: / or C:\.

If both syslog and logfile are given that last specified option will be used.

--verbose and --quiet are additive. The default is to print warnings and above only. Available log-levels are 'mute', 'critical, 'error', 'warning' and 'info'.

The --features option allows one to enable or disable /seek and /index http-handlers and change their respone: The 'flatindex' option concerns /index&flatindex=1 which recursively indexes all video file. It is disabled by defaults since a recursive search of the default docroot / can takes a very long time. When requesting png or jpeg images harvid decodes a raw RGB frame and then encodes it again. If 'keepraw' feature is enabled, both the raw RGB and encoded image are kept in cache. The default is to invaldate the RGB frame after encoding the image.
