     >>> ls(distbin)

+Like for console_scripts, the output is a list of the scripts
+generated. Likewise, on windows two files, an ``.exe`` and a script with
+``-script.py`` appended, are generated:
+
+    >>> import os, sys
+    >>> if sys.platform == 'win32':
+    ...     scripts == [os.path.join(distbin, 'distutilsscript.exe'),

 It also works for zipped eggs:
