description = """
This module is the EasyBuild toolchain that uses the Cray compiler wrapper with
the gcc-native compiler activated. The components loaded are those of the Cray Programming
Environment (CPE) version 25.03.

The module has the same effect as loading PrgEnv-gnu and cpe/25.03 should have, but
does not use either of those modules. The use of PrgEnv-gnu is avoided since the
modules that it loads may change over time, reducing reproducibility, while loading
cpe/21.04 is avoided as this module is buggy and conflicts with the way the LUMI
software stack currently works. Instead, the module declares itself a member of
the PrgEnv family and sets an PE_ENV which would otherwise be set by PrgEnv-gnu,
ensuring that the Cray PE will work as if those modules are loaded.
