It is written in Perl in a functional-recurisive way, featuring full AUR dependencies support.
Being written in Perl (or any other language, except bash), it means that it can't execute/source (silently) the PKGBUILD to get information for a package, which guarantees an extra-level of security. Other benefits are the performance and power that comes with Perl.
