'''Define the policy for the Liu sandbox
 
This policy is set up to support Python2 and Python3 programs that
execute from within a working directory in the /tmp file system under the
Liu sandbox (see http://openjudge.net/~liuyu/Project/LibSandbox).
It assumes a 64-bit execution environment.
It allows file I/O only to that directory and to a set of directories
passed into the constructor call. The latter set is specific to the
language being supported.
The allowed set of system calls has been determined experimentally
by observing Python2 and Python3 execution. It is entirely possible
that some other more-rare syscalls will be executed from within parts
of the Python library that have not yet been exercised.
An abortive attempt was made to support Matlab; the system calls that it
seems to need have been left in as comments for documentation purposes.

.. function:: which_files(file [, mode=os.F_OK | os.X_OK[, path=None[, pathext=None]]])
 
Generate full paths, where the *file* is accesible under *mode*
and is located in the directory passed as a part of the *file* name,
or in any directory on *path* if a base *file* name is passed.
 
The *mode* matches an existing executable file by default.
 
The *path* defaults to the ``PATH`` environment variable,
or to :const:`os.defpath` if the ``PATH`` variable is not set.
On Windows, a current directory is searched before directories in the ``PATH`` variable,
but not before directories in an explicitly passed *path* string or iterable.
 
The *pathext* is used to match files with any of the extensions appended to *file*.
On Windows, it defaults to the ``PATHEXT`` environment variable.
If the ``PATHEXT`` variable is not set, then the default *pathext* value is hardcoded
for different Windows versions, to match the actual search performed on command execution.
On Windows <= 4.x, ie. NT and older, it defaults to '.COM;.EXE;.BAT;.CMD'.
On Windows 5.x, ie. 2k/XP/2003, the extensions '.VBS;.VBE;.JS;.JSE;.WSF;.WSH' are appended,
On Windows >= 6.x, ie. Vista/2008/7, the extension '.MSC' is further appended.
The actual search on command execution may differ under Wine_,
which may use a `different default value`__, that is `not treated specially here`__.
In each directory, the *file* is first searched without any additional extension,
even when a *pathext* string or iterable is explicitly passed.
