To be honest I can't remember when I last used Perl but this publication brought back a few memories DOI.

HackaMol is an open source, object-oriented toolkit written in Modern Perl that organizes atoms within molecules and provides chemically intuitive attributes and methods.

Source code and example scripts are available online at http:// github.com/demianriccardi/HackaMol. There is also a description of an IPerl Notebook in the supporting information.

There is also a very interesting extension HackaMol::X::Vina, a structured class that provides an interface with the AutoDock Vina docking program
