-.Sh NAME
-.Nm symorder
-.Nd rearrange name list
-.Sh SYNOPSIS
-.Nm
-.Op Fl c
-.Op Fl m
-.Op Fl t
-.Op Fl x Ar excludelist
-.Ar symlist file
-.Sh DESCRIPTION
-The file
-.Ar symlist
-contains a list of symbols to be found in
-.Ar file ,
-one symbol per line.
-.Pp
-The symbol table of
-.Ar file
-is updated in place;
-symbols read from
-.Ar symlist
-are relocated to the beginning of the table and in the order given.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl c
-Make all any symbols not in
-.Ar symlist
-local to this file.
-.It Fl t
-Restrict the symbol table to the symbols listed in
-.Ar symlist .
-.It Fl x Ar excludelist
-Exclude the symbols listed in
-.Ar excludelist
-from the symbol table.
-.It Fl m
-Exit with status zero, even if some symbols are missing.
-.El
-.Pp
-This program was specifically designed to cut down on the
-overhead of getting symbols from
-.Pa /boot/kernel/kernel .
-.Sh DIAGNOSTICS
-The
-.Nm
-utility exits 0 on success, 1 if a symbol
-listed in the
-.Ar symlist
-file was not found in the symbol
-table, and >1 if an error occurs.
-.Sh SEE ALSO
-.Xr nm 1 ,
-.Xr strip 1 ,
-.Xr nlist 3
-.Sh HISTORY
-The
-.Nm
-utility appeared in
-.Bx 3.0 .
