-.SH "GLOBAL PREFERENCES"
-These are the values set with \fBset\-global\fR.
-.TP
-.B required\-tags
-If this is set an nonempty then randomly played tracks will always have at
-least one of the listed tags.
-.TP
-.B prohibited\-tags
-If this is set an nonempty then randomly played tracks will never have any of
-the listed tags.
-.TP
-.B playing
-If unset or \fByes\fR then play is enabled.
-Otherwise it is disabled.
-Use \fBdisable\fR rather than setting it directly.
-.TP
-.B random\-play
-If unset or \fByes\fR then random play is enabled.
-Otherwise it is disabled.
-Use \fBdisable\fR rather than setting it directly.
-.PP
-Global preferences starting '_' are read-only (in the sense that you cannot
-modify them; the server may modify them as part of its normal operation).
-They are:
-.TP
-.B _dbversion
-The database version string.
-This is used by DisOrder to detect when it must
-modify the database after an upgrade.
-.SH "LIBAO DRIVER"
-.SS "Raw Protocol Players"
-Raw protocol players are expected to use the \fBdisorder\fR libao driver.
-Programs that use libao generally have command line options to select the
-driver and pass options to it.
-.SS "Driver Options"
-The known driver options are:
-.TP
-.B fd
-The file descriptor to write to.
-If this is not specified then the driver looks like the environment
-variable \fBDISORDER_RAW_FD\fR.
-If that is not set then the default is 1 (i.e. standard output).
-.TP
-.B fragile
-If this is set to a nonzero value then the driver will call \fB_exit\fR(2) if a
-write to the output file descriptor fails.
-This is a workaround for buggy players such as \fBogg123\fR that ignore
-write errors.
