+"""
+SVN helper script.
+
+Try to set the svn:eol-style property to "native" on every .py, .txt, .c and
+.h file in the directory tree rooted at the current directory.
+
+Files with the svn:eol-style property already set (to anything) are skipped.
+
+svn will itself refuse to set this property on a file that's not under SVN
+control, or that has a binary mime-type property set.  This script inherits
+that behavior, and passes on whatever warning message the failing "svn
+propset" command produces.
+
+In the Python project, it's safe to invoke this script from the root of
+a checkout.
+
+No output is produced for files that are ignored.  For a file that gets
+svn:eol-style set, output looks like:
+
+    property 'svn:eol-style' set on 'Lib\ctypes\__init__.py'
+
+For a file not under version control:
+
+    svn: warning: 'patch-finalizer.txt' is not under version control
+
+and for a file with a binary mime-type property:
+
+    svn: File 'Lib\test\test_pep263.py' has binary mime type property
