This document discusses Mojolicious, a lightweight web framework for Perl. It provides examples of using Mojolicious to quickly generate a new project skeleton, start a web server, and add routing and templates. The document also lists some advantages of Mojolicious like its small core dependencies, quick prototyping capabilities, and ability to scale from simple to more complex applications.

- 14. extremely quick and dirty ideal for prototyping

- 21. and once you grow out of the lite_app
- 22. mojolicious in?ate new_project
