+- `manylinux-platforms`: Array of [manylinux](https://github.com/pypa/manylinux)
+    specialization build targets for Linux Python module wheels. Manylinux "provides
+    a convenient way to distribute binary Python extensions as wheels on Linux";
+    see the [manylinux README](https://github.com/pypa/manylinux#manylinux) for more details.
+    An array entry includes both the name of the manylinux specialization, which is
+    related to the toolset to be used, and the platform architecture to target.
+    All supported specialization and architecture pairs are enabled by default
+    and listed in the example below, but can be disabled by removing them from the
+    input array in the calling external module workflow.
+    The array follows [JavaScript Object Notation (JSON)](https://www.json.org/json-en.html) syntax
+    and GHA jobs will launch in the order provided.
+    The array is formatted as '["<specialization>-<target_arch>","<specialization>-<target_arch>"]'.
+
+```yaml
+  with:
+    manylinux-platforms: '["_2_28-x64","2014-x64","_2_28-aarch64"]'
+```
