@@ -17,11 +19,68 @@ For every pathname, this command will list if each attr is 'unspecified',
 
 OPTIONS
 -------
+--stdin::
+       Read file names from stdin instead of from the command-line.
+
+-z::
+       Only meaningful with `--stdin`; paths are separated with
+       NUL character instead of LF.
+
 \--::
        Interpret all preceding arguments as attributes, and all following
        arguments as path names. If not supplied, only the first argument will
        be treated as an attribute.
 
+OUTPUT
+------
+
+The output is of the form:
+<path> COLON SP <attribute> COLON SP <info> LF
+
+Where <path> is the path of a file being queried, <attribute> is an attribute
+being queried and <info> can be either:
+
+'unspecified';; when the attribute is not defined for the path.
+'unset';;      when the attribute is defined to false.
+'set';;                when the attribute is defined to true.
+<value>;;      when a value has been assigned to the attribute.
+

+---------------
+*.java diff=java -crlf myAttr
+NoMyAttr.java !myAttr

+$ git check-attr crlf diff myAttr -- org/example/MyClass.java
+org/example/MyClass.java: crlf: unset
+org/example/MyClass.java: diff: java
+org/example/MyClass.java: myAttr: set
+---------------
+
+* Listing attribute for multiple files:
+---------------
+$ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
