     6  //
     7  // Description:
     8  //	lddfiles prints the arguments on the command line and all .so's
     9  //	on which they depend. In some cases, those .so's are actually symlinks;
    10  //	in that case, the symlink and its value are printed.
    11  //	lddfiles can be used to package up a command for tranporation to
    12  //	another machine, e.g.
    13  //	scp `lddfiles /usr/bin/*` remotehost:/
    14  //	will let you copy all of /usr/bin, and all needed libraries. to a remote
    15  //	host.
    16  //	lddfiles /usr/bin/* | cpio -H newc -o > /tmp/x.cpio
    17  //	lets you easily prepare cpio archives, which can be included in a kernel
    18  //	or similarly scp'ed to another machine.
