Implements minimal ActiveRecord models and database helper code used in both the Metasploit Framework (MSF) and Metasploit commercial editions.

Common code, such as validators and mixins, that are shared between ActiveModels in metasploit-framework and ActiveRecords in metasploit_data_models.

Automatically includes Modules from app/concerns/<module_with_concerns>/<concern>.rb into <module_with_concerns> to ease monkey-patching associations and validations on ActiveRecord::Base descendents from other gems when layering schemas.

Traces the belongs_to associations on ActiveRecord::Base descendants to find the minimum cluster in which all foreign keys are fulfilled in the Entity-Relationship Diagram.

YARD plugin that uses metasploit-erd to add Entity-Relationship Diagrams to each namespace Module and ActiveRecord::Base subclass's documentation.

Metasploit::Version::Full for deriving String VERSION from constants in Version module and shared examples: 'Metasploit::Version VERSION constant' to check VERSION and 'Metasploit::Version Version Module' to check Version.
