Warner Losh fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

.Sh NAME
.Nm lorder
.Nd list dependencies for object files
.Sh SYNOPSIS
.Nm
.Ar
.Sh DESCRIPTION
The
.Nm
utility uses
.Xr nm 1
to determine interdependencies in the list of object files
and library archives
specified on the command line.
The
.Nm
utility outputs a list of file names where the first file contains a symbol
which is defined by the second file.
.Pp
The output is normally used with
.Xr tsort 1
when a library is created to determine the optimum ordering of the
object modules so that all references may be resolved in a single
pass of the loader.
.Pp
When linking static binaries,
.Nm
and
.Xr tsort 1
can be used to properly order library archives automatically.
.Sh ENVIRONMENT
.Bl -tag -width indent
.It Ev NM
Path to the
.Xr nm 1
binary, defaults to
.Dq Li nm .
.It Ev NMFLAGS
Flags to pass to
.Xr nm 1 .
.El
.Sh EXAMPLES
.Bd -literal -offset indent
ar cr library.a `lorder ${OBJS} | tsort`
cc -o foo ${OBJS} `lorder ${STATIC_LIBS} | tsort`
