+Environ Management Tests
+------------------------
+
+Tests for items in the "MPI Environmental Management" chapter.
+
+These are begin created in the ompi-tests-public repository
+to ensure they are easy to access.
+
+Using autotools to detect if we have the MPI-4.1 remove error code
+functionality, otherwise skips.
+
+Usage
+-----
+ - Ensure MPI `mpicc` in `PATH`
+ - Run autogen/configure/make to build test
+
+   ```
+     cd environ-mgmt/
+     ./autogen.sh && ./configure && make
+   ```
+
+ - Run test(s)
+
+   ```
+     mpirun -np 1 ./src/test_add_del_err_codes
+   ```
+
+Example Output
+--------------
+
+ - On MPI 3.x
+    ```
+    laptop:$ mpirun -np 1 ./src/test_add_del_err_codes
+    TEST: Success creating error class/code/string (last=92, newlast=94)
+    ==== Adds done ====
+    ==== Remove estring ====
+    Warning: MPI_Remove_error_xxx code/class/string NOT available!
+    ==== Remove ecode ====
+    Warning: MPI_Remove_error_xxx code/class/string NOT available!
+    ==== Remove eclass  ====
+    Warning: MPI_Remove_error_xxx code/class/string NOT available!
+    DONE: Success
+    laptop$ echo $?
+    0
+    laptop$
+    ```
+
+ - On MPI 4.1 or later
+    ```
+    laptop:$ mpirun -np 1 ./src/test_add_del_err_codes
+    TEST: Success creating error class/code/string (last=92, newlast=94)
+    ==== Adds done ====
+    ==== Remove estring ====
+    ==== Remove ecode ====
+    TEST: Success reomved error code (oldlast=94, newlast=93)
+    ==== Remove eclass  ====
+    TEST: Success reomved error class (oldlast=93, newlast=92)
+    DONE: Success
+    laptop$ echo $?
+    0
+    laptop$
+    ```
