 Perl has three standard install locations: **core**, **vendor**, and **site**. Here, **core** is used only for the perl itself, **vendor** is used for installing any other conda-forge packages, and **site** is used for the user to install things locally from sources other than conda-forge.
 
-The most commonly used build system for `perl packages <https://github.com/conda-forge/perl-file-which-feedstock>`__ is ``ExtUtils::MakeMaker``.

+Notable here is ``INSTALLDIRS=vendor``, which selects the appropriate install location for a conda-forge package, and the ``NO_PERLLOCAL`` and ``NO_PACKLIST`` switches, which suppress various CPAN tracking files that are unnecessary when the module is being externally packaged via conda.
