 Because @code{defmath} itself uses the extensions, user-written code
 generally always executes with the extensions already loaded, so
 normally you can use any Calc function and be confident that it will
 be autoloaded for you when necessary.  If you are doing something
 special, check carefully to make sure each function you are using is
-from @file{calc.el} or its components, and call @samp{(calc-extensions)}
-before using any function based in @file{calc-ext.el} if you can't
