 APR::Request::Brigade
 
+This class is derived from APR::Brigade, providing additional
+methods for TIEHANDLE, READ and READLINE.  To be memory efficient,
+these methods delete buckets from the brigade as soon as their
+data is actually read, so you cannot C<seek> on handles tied to
+this class.  Such handles have semantics similar to that of a
+read-only socket.
+
 
 
 
 =head2 new, TIEHANDLE
 
+    APR::Request::Brigade->TIEHANDLE($bb)
+
+Creates a copy of the bucket brigade represented by $bb, and
+blesses that copy into the APR::Request::Brigade class.  This
+provides syntactic sugar for using perl's builtin C<read>, C<readline>,
+and C<< <> >> operations on handles tied to this package:
+
+    use Symbol;
+    $fh = gensym;
+    tie *$fh, "APR::Request:Brigade", $bb;
+    print while <$fh>;
+
 
 
 
 =head2 READ
 
+    $bb->READ($contents)
+    $bb->READ($contents, $length)
+    $bb->READ($contents, $length, $offset)
+
+Reads data from the brigade $bb into $contents.  When omitted
+$length defaults to C<-1>, which reads the first bucket into $contents.
+A positive $length will read in $length bytes, or the remainder of the
+brigade, whichever is greater. $offset represents the index in $context
+to read the new data.
+
 
 
 
 =head2 READLINE
 
+    $bb->READLINE()
+
+Returns the first line of data from the bride. Lines are terminated by
+linefeeds (the '\012' character), but we may eventually use C<$/> instead.
