+
+     MIN_NEEDED_INPUT	minimal number of input bytes needed for the next
+			conversion.
+     MIN_NEEDED_OUTPUT	minimal number of bytes produced by the next round
+			of conversion.
+
+     MAX_NEEDED_INPUT	you guess it, this is the maximal number of input
+			bytes needed.  It defaults to MIN_NEEDED_INPUT
+     MAX_NEEDED_OUTPUT	likewise for output bytes.
+
+   Both values have a default of 1.
+
+     LOOPFCT		name of the function created.  If not specified
+			the name is `loop' but this prevents the use
+			of multiple functions in the same file.
+
+     COUNT_CONVERTED	optional macro which is used to count the actual
+			number of characters converted.  For some conversion
+			it is easy to compute the value afterwards, but for
+			others explicit counting is cheaper.
+
+     BODY		this is supposed to expand to the body of the loop.
