 Assert was developed primarily with `gfortran` 11.2.0 and `nagfor` 7.1.
 Recent versions of the Cray and Intel compilers should also suffice.

 The following command builds Assert and runs the full test suite in a single image:
 ```
 fpm test

 where `fpm test` builds the Assert library and runs the test suite, including the tests.

+### Building and testing with the Cray Compiler Environment (CCE)
+Because `fpm` uses the compiler name to determine the compiler identity and because
+CCE provides one compiler wrapper, `ftn`, for invoking all compilers, you will
+need to invoke `ftn` in a shell script named to identify CCE compiler. For example,
+place a script named `crayftn.sh` in your path with the following contents and with
+executable privileges set appropriately:
+```
+#!/bin/bash
+
+ftn $@
+```
+Then build and test Assert with the command
+```
+fpm test --compiler crayftn.sh
+```
