+'''perform automatic newline conversion
+
+  Deprecation: The win32text extension requires each user to configure
+  the extension again and again for each clone since the configuration
+  is not copied when cloning.
+
+  We have therefore made the ``eol`` as an alternative. The ``eol``
+  uses a version controlled file for its configuration and each clone
+  will therefore use the right settings from the start.
+
+To perform automatic newline conversion, use::
+
+  [extensions]
+  win32text =
+  [encode]
+  ** = cleverencode:
+  # or ** = macencode:
+
+  [decode]
+  ** = cleverdecode:
+  # or ** = macdecode:
+
+If not doing conversion, to make sure you do not commit CRLF/CR by accident::
+
+  [hooks]
+  pretxncommit.crlf = python:hgext.win32text.forbidcrlf
+  # or pretxncommit.cr = python:hgext.win32text.forbidcr
+
+To do the same check on a server to prevent CRLF/CR from being
+pushed or pulled::
+
+  [hooks]
+  pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
+  # or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
