Supports multiple variable file formats (JSON, YAML, TOML, INI, XML, CSV) with automatic discovery, and allows extending Jinja with custom filters and tests via Python extension modules. Integrates directly into build systems like Make, CMake, and SCons through Makefile dependency generation (`-M`, `-MD` flags), originally developed for embedded code generation from CMSIS-SVD hardware descriptions.
