Simple policy for file I/O functions
This defines the policy for file I/O with modules such as FileSlurpWithinPolicy. The purpose is to allow systems administrators to define locations and restrictions for applications’ file I/O and give app developers a policy to follow. Note that the module doesn’t ENFORCE the policy - application developers can choose to ignore it and systems administrators can choose not to install their applications if they do!.
You may control which policy gets applied by creating a FilePolicyConfig module with an IMPLEMENTATION constant. You may write your own policy as a module within the FilePolicy namespace.
By default if no FilePolicyConfig is present, the FilePolicyDefault policy gets applied which doesn’t impose any restrictions and provides reasonable default locations for temporary and log files.
