class OperatingSystem:
"""Base class for all the Operating Systems.
On a multiple architecture machine, the architecture spec field can be set to
build a package against any target and operating system that is present on the
platform. On Cray platforms or any other architecture that has different front
and back end environments, the operating system will determine the method of
compiler detection.
There are two different types of compiler detection:
1. Through the $PATH env variable (front-end detection)
2. Through the module system. (back-end detection)
Depending on which operating system is specified, the compiler will be detected
using one of those methods.
For platforms such as linux and darwin, the operating system is autodetected.
