The document discusses Composer, a dependency management tool for PHP projects. It explains that Composer allows developers to declare dependencies in a composer.json file and have them automatically installed. Some key points made include: - Composer is not a new concept, similar tools exist for Node.js and Ruby - Composer addresses some limitations of PEAR for dependency management - To use Composer, install it locally and define dependencies in composer.json - Running 'composer install' will download and install all listed dependencies - Composer downloads dependencies from Packagist, a central repository - Developers can publish their own packages to Packagist for others to use

15. Composer is a tool for dependency management in PHP.
It allows you to declare the dependent libraries your project needs and it will
install them in your project for you.

22. But, what about PEAR?

23. But, what about PEAR?
• You have to install it in all the system

24. But, what about PEAR?
• You have to install it in all the system
• You can´t see the source code

25. But, what about PEAR?
• You have to install it in all the system
• You can´t see the source code
• Don´t allow different repository sources

26. But, what about PEAR?
• You have to install it in all the system
• You can´t see the source code
• Don´t allow different repository sources
• Composer is compatible with PEAR, :)
