+  description: |
+    This feedstock packages the Gazebo Classic simulator, that will not be supported past 2025. 
+    For new development, please consider migrating to Modern gz-sim simulator, available in conda-forge.
+    To simplify migration to gz-sim, we want to permit to side-by-side installation of gazebo and libgz-tools2, however they both install a command called `gz`. 
+    So, this feedstock is building two different variants of the `gazebo` conda package:
+      * One that contains `origname` in its build string that has higher priority and is installed if libgz-tools2 is not installed, that uses `gz` as the name for the cli helper of gazebo classic. This variant cannot be installed if `libgz-tools2` is installed. For forward compatibility, this variant also installs a `gz11` command.
+      * One that contains `gzcompatname` that is co-installable with libgz-tools2, but that renames the `gz` commmand line tool to `gz11`.
