/* Ho ho. We are not the program interpreter! We are the program
itself! This means someone ran ld.so as a command. Well, that
might be convenient to do sometimes. We support it by
interpreting the args like this:
ld.so PROGRAM ARGS...
The first argument is the name of a file containing an ELF
executable we will load and run with the following arguments.
To simplify life here, PROGRAM is searched for using the
normal rules for shared objects, rather than $PATH or anything
like that. We just load it and use its entry point; we don't
pay attention to its PT_INTERP command (we are the interpreter
ourselves). This is an easy way to test a new ld.so before
installing it. */

_dl_sysdep_fatal ("\
Usage: ld.so [--list] EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]\n\
You have invoked `ld.so', the helper program for shared library executables.\n\
This program usually lives in the file `/lib/ld.so', and special directives\n\
in executable files using ELF shared libraries tell the system's program\n\
loader to load the helper program from this file. This helper program loads\n\
the shared libraries needed by the program executable, prepares the program\n\
to run, and runs it. You may invoke this helper program directly from the\n\
command line to load and run an ELF executable file; this is like executing\n\
that file itself, but always uses this helper program from the file you\n\
specified, instead of the helper program file specified in the executable\n\
file you run. This is mostly of use for maintainers to test new versions\n\
