to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

|
.Sh DESCRIPTION
|
|
.Nm
|
|
prints the contents of object files and final linked images named on the
|
|
command line.
|
|
If no file name is specified,
|
|
.Nm
|
|
will attempt to read from
|
|
.Pa a.out .
|
|
If
|
|
.Pa -

is used as a file name,
|
|
.Nm
|
|
will process a file on its standard input stream.
|
|
.Nm
|
