Actually describe all of the command line options in fsinfo(8).

Most of the text was take from the fsinfo section in info(1).
Also included a pointer to that information, since there is
so much detail about the format of the configuration files there.

 .Sh DESCRIPTION
 The
 .Nm
 utility takes a set of system configuration information, and generates
 a co-ordinated set of
 .Xr amd ,
-.Xr mount ,
+.Xr mount
 and
 .Xr mountd
 configuration files.
 .Pp
+The following options are available:
+.Bl -tag -width Fl
+.It Fl a Ar autodir
+Specifies the directory name in which to place the automounter's
+mount points.  This defaults to
+.Pa /a .
+.It Fl b Ar bootparams_prefix
+Specifies the prefix for the 
+.Pa bootparams
+file.  If it is not given, then the file will not be generated.
+The file will be constructed for the destination machine and will be
+placed into a file named
+.Pa bootparams
+and prefixed by the
+.Ar bootparams_prefix
+string.
+The file generated contains a list of entries describing each
+diskless client that can boot from the destination machine.
+.It Fl d Ar dumpsets_prefix
+Specifies the prefix for the
+.Pa dumpsets
+file.  If it is not specified, then the file will not be generated.
+The file will be for the destination machine and will be placed into a file
+named
+.Pa dumpsets
+prefixed by the
+.Ar dumpsets_prefix
+string.
+This file is for use by
+.Tn Imperial College's
+local backup system.
+.It Fl e Ar exports_prefix
+Defines the prefix for the
+.Pa exports
+files.  If it is not given, then the file will not be generated.
+For each machine defined in the configuration files as having disks,
+and
+.Pa exports
+file is constructed and given a file name determined by the name of the
+machine, prefixed with the
+.Ar exports_prefix
+string.
+If a machine is defined as diskless, then no
+file will be created for it.  The files contain entries
+for directories on the machine that may be exported to clients.
+.It Fl f Ar fstabs_prefix
+This defines the prefix for the
+.Pa fstab
+files.  The files will only be created if this prefix is defined.
+For each machine defined in the configuration files, a
+.Pa fstab
+file is created with the file name determined by prefixing this
+.Ar fstabs_prefix
+string with the name of the machine.  These files contain entries
+for filesystems and partitions to mount at boot time.
+.It Fl h Ar hostname
+Defines the hostname of the destination machine to process for.
+If this is not specified, it defaults to the local machine name,
+as returned by
+.Xr gethostname 3 .
+.It Fl m Ar automounts_prefix
+Defines the prefix for the automounter files.  The maps will
+only be produced if this option is specified.  The mount maps
+suitable for the network defined by the configuration files will
+be placed into files with names calculated by prefixing the
+.Ar automounts_prefix
+string to the name of each map.
+.It Fl q
+Selects quite mode.  Only error messages that are generated will
+be displayed.
+.It Fl v
+Selects verbose mode.  When this is activated, more messages
+will be displayed, and all information discovered when performing the semantic
+analysis phase will be displayed.  Each verbose message
+is output to the standard output on a line starting with a `#'
+character.
+.It Fl D Ar name[=string]
+Defines a symbol
+.Ar name
+for the preprocessor when reading the configuration files.
+Equivalent to the
+.Em #define
+directive.
+.It Fl I Ar dir
+This option is passed into the preprocessor for the configuration
+files.  It specifies directories in which to find include files.
+.It Fl U Ar name
+Removes and initial definition of the symbol
+.Ar name .
+Inverse of the
+.Fl D
+option.
+.It Ar config
+One or more configuration files to be passed as input to 
+.Nm fsinfo .
