The document discusses the various plugins available for Dancer, a web development framework for Perl. It tells a story about a Perl web developer named Joe who is working on an important new project and finds that there is a Dancer plugin to meet nearly all of his needs, such as templates, logging, authentication, databases, APIs, email, social media, and more. It also notes that if a needed plugin does not already exist, new ones can be easily created due to Dancer's modular architecture.
