+.Nd add symbol files
+.Sh SYNOPSIS
+.Nm
+.Op Fl akx
+.Op Ar modules-path Op Ar outfile
+.Sh DESCRIPTION
+By default,
+.Nm
+reads
+.Nm kldstat
+output from standard input and writes to standard output a list of
+.Nm gdb
+commands to add symbol files from klds in subdirectories of the subdirectory
+.Ar modules
+of the current directory, which is intended to be a kernel build directory.
+This enables
+.Nm gdb
+to load the symbols into the debugging environment.
+.Pp
+If
+.Pa modules-path 
+is specified,
+.Nm
+uses it for the modules directory instead of the default
+.Pa modules .
+This is useful when building in a non-standard location (i.e. not 
+.Pa /usr/src
+and
+.Pa /usr/obj ).
+.Pp
+If
+.Pa outfile
+is specified,
+.Nm 
+writes to it instead of standard output.
+.Sh OPTIONS
+The following options modify the function of
+.Nm :

+.It Fl k
+Instead of reading from standard input, start a
+.Nm kldstat
+and read the information from it.
+.It Fl x
+Normally
+.Nm 
+looks for klds with names of the form
+.Pa module.ko.debug .
+The
+.Fl x
+option tells
+.Nm
+to look for klds with names of the form
+.Pa module.ko .

+.Sh HISTORY
+.Nm
+first appeared in 
+.Fx 5.0 .
+.Sh AUTHORS
+.An Greg Lehey Aq grog@FreeBSD.org
+.Sh BUGS
+It should be possible to write to an outfile without specifying a module path.
