It is used a lot in cfg-common.h.
The usage (the whole config system) is the same between filters
and the "main" mplayer options.
Also from the config parsing side it should just be a matter of
changing the variable type from "int" to "char *" when you want
a CONF_TYPE_STRING instead of CONF_TYPE_INT.
