What is DLTK?

Dynamic Languages Toolkit (DLTK) is a tool for vendors, researchers, plug-in or tool writters and end-users who rely on dynamic languages. DLTK is comprised of a set of extensible frameworks designed to reduce the complexity of building full featured development environments for dynamic languages such as PHP, JavaScript and Perl. Dynamic Languages Toolkit 2.0 requires Eclipse Platform 3.5 or later[3].
