simple policy for file I/O functions

File::Policy defines the policy for file I/O with modules such as File::Slurp::WithinPolicy. 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 File::Policy::Config module with an IMPLEMENTATION constant. You may write your own policy as a module within the File::Policy:: namespace.

By default (if no File::Policy::Config is present), the File::Policy::Default policy gets applied which doesn't impose any restrictions and provides reasonable default locations for temporary and log files.

The motivation behind this module was a standard, flexible approach to allow a site wide file policy to be defined. This will be most useful in large environments where a few sysadmins are responsible for code written by many other people. Simply ensuring that submitted code calls check_safe() ensures file access is sane, reducing the amount of effort required to do a security audit.
