+USING ATTRIBUTE MACROS
+----------------------
+
+You do not want any end-of-line conversions applied to, nor textual diffs
+produced for, any binary file you track.  You would need to specify e.g.
+
+------------
+*.jpg -crlf -diff
+------------
+
+but that may become cumbersome, when you have many attributes.  Using
+attribute macros, you can specify groups of attributes set or unset at
+the same time.  The system knows a built-in attribute macro, `binary`:
+
+------------
+*.jpg binary
+------------
+
+which is equivalent to the above.  Note that the attribute macros can only
+be "Set" (see the above example that sets "binary" macro as if it were an
+ordinary attribute --- setting it in turn unsets "crlf" and "diff").
+
+
+DEFINING ATTRIBUTE MACROS
+-------------------------
+
+Custom attribute macros can be defined only in the `.gitattributes` file
+at the toplevel (i.e. not in any subdirectory).  The built-in attribute
+macro "binary" is equivalent to:
+
+------------
+[attr]binary -diff -crlf
+------------
