This document discusses Mojolicious::Lite, a micro web application framework for Perl. It begins by introducing Mojolicious::Lite and positioning it as a framework for small, single-file web apps as opposed to production or complex applications. It then provides an example of a simple Mojolicious::Lite app and explains key aspects like routes, templates, and starting the app. Finally, it briefly mentions some similar Perl web frameworks and provides additional resources.
