# Blender.sys module

"""
The Blender.sys submodule.

sys
===

B{New}: L{exists}

This module provides a minimal set of helper functions and data.  Its purpose
is to avoid the need for the standard Python module 'os', in special 'os.path',
though it is only meant for the simplest cases.

Example::

  import Blender

  filename = ""
  def f(name): # file selector callback
    global filename
    filename = name

  Blender.Window.FileSelector(f)

  if filename:
    print 'basename:', Blender.sys.basename(filename)
    print 'dirname:',  Blender.sys.dirname(filename)
    print 'splitext:', Blender.sys.splitext(filename)

  # what would basename(splitext(filename)[0]) print?

@type sep: char
@var sep: the platform-specific dir separator for this Blender: '/'
    everywhere, except on Win systems, that use '\\'. 
@type dirsep: char
@var dirsep: same as L{sep}.
@type progname: string
@var progname: the Blender executable (argv[0]).

@attention: The module is called sys, not Sys.
