+  description: |
+    IREGI is a package for one-loop tensor Integral REduction with General
+    propagator Indices.
+
+    The algorithm was proposed by G. Duplancic, B. Nizic
+    (DOI: [10.1140/epjc/s2004-01723-7](https://doi.org/10.1140/epjc/s2004-01723-7)).
+
+    This implementation for MADLOOP5 in MadGraph5_aMC@NLO was originally
+    authored by Hua-Sheng Shao.
+  # IREGI source only exists in the MG5_aMC@NLO repo and so has the same license
