+## Revision 1.20  2002/08/20 19:33:21  geraint
+## Minor bug fixes and enhancements (I hope):
+##
+## Delimited expressions within function calls to prevent denominators from continuing beyond commas.
+## Allow latex to adjust size of parentheses according to expression within.
+## Replaced ^ with \uparrow (less misleading - latex maths doesn't understand operator precedence or words).
+## Replaced abs(x) with |x| when x does not contain brackets.
+##
 ## Revision 1.19  2002/08/19 14:37:05  geraint
