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