+# Migration support for python 3.10+
+
+## Intent
+
+Applications of patches will enable local use of newer python versions
+available with a recent OS install or package manager installation.
+Makefile targets will fail out of the box w/o modifying collection imports.
+
+Create new patches as needed to help testing along.
+Eventually this hierarchy can be dismantled once the latest interpreter
+is generally in use.
+
+## patches/
+
+This directory contains patch files that can be directly applied to sources
+in the python virtualenv directory.  Patches are created to support use of
+three python version variants for the robot ramework:
+    python 2x       (deprecated)
+    python >= 3.10  (collections.abc required)
+    python < 3.10   (collections.abc optional)
+
+
+# vst_venv/
+
+Makefile will first create a python virtualenv directory to selectively
+use packages.  After setup patches are applied to venv (as a transition)
+to fully enable support for local interpreter use for newer OS installs.
+
+
+# staging/
+
+The staging directory is used for comparison with the vst_venv directory
+to generate patches.  Populate the directory with a copy of a cleanly
+patched virtual interpreter then modify files benath/ staging to generate
+a patch from.
