+# This file mainly controls line ending conversion behaviour, if
+# the user has the setting core.autocrlf true.

+# The meaning of the attributes is a little odd
+# -crlf means DO NOT convert line endings
+# crlf means CONVERT to lf in the repo & Linux/Mac, crlf on Windows
+
+# sln is always CRLF, even on linux, so don't convert
