+# This is an example of a distutils 'setup' script for the example_nt
+# sample.  This provides a simpler way of building your extension
+# and means you can avoid keeping MSVC solution files etc in source-control.
+# It also means it should magically build with all compilers supported by
+# python.
+
+# USAGE: you probably want 'setup.py install' - but execute 'setup.py --help'
+# for all the details.
+
+# NOTE: This is *not* a sample for distutils - it is just the smallest
+# script that can build this.  See distutils docs for more info.
