-            ### line endings
-            - explain the difference: Windows CRLF, everyone else LF, some
-              accept only LF
-            - maintainers may reject contributions because of line endings
-            - on Windows, git can do it for you, via `dos2unix`
-            - fine grained control with `man 5 gitattributes`
