38.Sh NAME
39.Nm lorder
40.Nd list dependencies for object files
41.Sh SYNOPSIS
42.Nm
43.Ar
44.Sh DESCRIPTION
45The
46.Nm
47utility uses
48.Xr nm 1
49to determine interdependencies in the list of object files
50and library archives
51specified on the command line.
52The
53.Nm
54utility outputs a list of file names where the first file contains a symbol
55which is defined by the second file.
56.Pp
57The output is normally used with
58.Xr tsort 1
59when a library is created to determine the optimum ordering of the
60object modules so that all references may be resolved in a single
61pass of the loader.
62.Pp
63When linking static binaries,
64.Nm
65and
66.Xr tsort 1
67can be used to properly order library archives automatically.
