PatchELF is simple utility for modifing existing ELF executables and
libraries. In particular, it can do the following:
* Change the dynamic loader ("ELF interpreter") of executables:
$ patchelf --set-interpreter /lib/my-ld-linux.so.2 my-program
* Change the RPATH of executables and libraries:
$ patchelf --set-rpath /opt/my-libs/lib:/other-libs my-program
* Shrink the RPATH of executables and libraries:
$ patchelf --shrink-rpath my-program
This removes from the RPATH all directories that do not contain a
library referenced by DT_NEEDED fields of the executable or library.
For instance, if an executable references one library libfoo.so, has
an RPATH "/lib:/usr/lib:/foo/lib", and libfoo.so can only be found
in /foo/lib, then the new RPATH will be "/foo/lib".

BUGS
Currently setting the RPATH on libraries ("--set-rpath") will usually
fail if the new RPATH is longer then the old RPATH.
