The Alfresco Module Management Tool (MMT) is a command-line utility (alfresco-mmt.jar) specifically designed to manage Alfresco Module Packages (AMPs). Its primary functions are to install new modules into an Alfresco WAR file (e.g., alfresco.war, share.war), list the modules that are currently installed, and uninstall modules. This tool is essential for applying customizations, add-ons, or patches that are distributed in the AMP format. It directly modifies the web application archive to include or remove the module's files.

A. The Environment Validation Tool (EVT) is used to check if a server environment meets the prerequisites for an Alfresco installation or upgrade, not for managing modules.

B. The Alfresco Support Tool (AST) is used to collect system information, logs, and configuration details into a single ZIP file for troubleshooting with Alfresco Support.

D. The Alfresco Java Foundations API (AJF) is a set of Java APIs for developers to build customizations, not a tool for installing pre-packaged modules.
