   4 SVN helper script.
   5
   6 Try to set the svn:eol-style property to "native" on every .py, .txt, .c and
   7 .h file in the directory tree rooted at the current directory.
   8
   9 Files with the svn:eol-style property already set (to anything) are skipped.
  10
  11 svn will itself refuse to set this property on a file that's not under SVN
  12 control, or that has a binary mime-type property set.  This script inherits
  13 that behavior, and passes on whatever warning message the failing "svn
  14 propset" command produces.
  15
  16 In the Python project, it's safe to invoke this script from the root of
  17 a checkout.
  18
  19 No output is produced for files that are ignored.  For a file that gets
  20 svn:eol-style set, output looks like:
  21
  22     property 'svn:eol-style' set on 'Lib\ctypes\__init__.py'
  23
  24 For a file not under version control:
  25
  26     svn: warning: 'patch-finalizer.txt' is not under version control
  27
  28 and for a file with a binary mime-type property:
  29
  30     svn: File 'Lib\test\test_pep263.py' has binary mime type property
