+Use Docker container to build an RPM.
+Using Docker approach to ensure a consistent and isolated build environment.
+
+Requirement: The `toml` Python package
+
+    pip install toml
+
+To run the script:
+
+    python build_rpm_docker.py
+
+This script will generate the RPM package files and place them in the
+dist/rpmbuild/ directory.
+
+Once the RPM package is generated, you can install it using:
+
+    sudo dnf install /path/to/<dejacode>.rpm
+
+(Replace the above path with the actual path to the generated RPM file.)
