    - XML::Simple, a Perl module: [`pkgs/top-level/perl-packages.nix`](top-level/perl-packages.nix) (search for the `XMLSimple` attribute). Most Perl modules are so simple to build that they are defined directly in `perl-packages.nix`; no need to make a separate file for them.
 
-   - Adobe Reader: [`pkgs/applications/misc/adobe-reader/default.nix`](applications/misc/adobe-reader/default.nix). Shows how binary-only packages can be supported. In particular the `postFixup` phase uses `patchelf` to set the RUNPATH and ELF interpreter of the executables so that the right libraries are found at runtime.

In particular, the `autoPatchelfHook` is used to set the RUNPATH and ELF interpreter of the executables so that the right libraries are found at runtime.
