+PatchELF is a 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".

+HOMEPAGE

+http://nixos.org/patchelf.html
+
+
+BUGS
+
+The `strip' command from binutils generated broken executables when
+applied to the output of patchelf (if `--set-rpath' or
+`--set-interpreter' with a larger path than the original is used).
+This appears to be a bug in binutils
+(http://bugs.strategoxt.org/browse/NIXPKGS-85).
+
+
+RELEASE HISTORY
+
+0.6 (November 7, 2011):
+
+* Hacky support for executables created by the Gold linker.
+
+* Support segments with an alignment of 0 (contributed by Zack
+  Weinberg).
+
+* Added a manual page (contributed by Jeremy Sanders
+  <jeremy@jeremysanders.net>).
+
+0.5 (November 4, 2009):
+
+* Various bugfixes.
+
+* `--force-rpath' now deletes the DT_RUNPATH if it is present.
+
+0.4 (June 4, 2008):
+
+* Support for growing the RPATH on dynamic libraries.
+
+* IA-64 support (not tested) and related 64-bit fixes.
+
+* FreeBSD support.
+
+* `--set-rpath', `--shrink-rpath' and `--print-rpath' now prefer
+  DT_RUNPATH over DT_RPATH, which is obsolete.  When updating, if both
+  are present, both are updated.  If only DT_RPATH is present, it is
+  converted to DT_RUNPATH unless `--force-rpath' is specified.  If
+  neither is present, a DT_RUNPATH is added unless `--force-rpath' is
+  specified, in which case a DT_RPATH is added.
+
+0.3 (May 24, 2007):
+
+* Support for 64-bit ELF binaries (such as on x86_64-linux).
+
+* Support for big-endian ELF binaries (such as on powerpc-linux).
+
+* Various bugfixes.
+
+0.2 (January 15, 2007):
+
+* Provides a hack to get certain programs (such as the
+  Belastingaangifte 2005) to work.
+
+0.1 (October 11, 2005):
+
+* Initial release.
