+In text mode, the default when reading is to convert platform-specific line
+endings (``\n`` on Unix, ``\r\n`` on Windows) to just ``\n``. When writing in
+text mode, the default is to convert occurrences of ``\n`` back to
+platform-specific line endings. This behind-the-scenes modification
to file data is fine for text files, but will corrupt binary data like that in
:file:`JPEG` or :file:`EXE` files. Be very careful to use binary mode when
reading and writing such files.
