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