## 7.9. Perl modules - `cpan.bbclass`

Recipes for Perl modules are simple. These recipes usually only need to point to the source's archive and then inherit the proper `.bbclass` file. Building is split into two methods depending on which method the module authors used.

Modules that use old `Makefile.PL`-based build system require `cpan.bbclass` in their recipes.

Modules that use `Build.PL`-based build system require using `cpan_build.bbclass` in their recipes.
