- (The NAMEs are not evaluated.)
- Options allow modification of the default behavior. Each option is a pair
- of an option keyword and a value form. Global options are specified before
- the first name, and affect all functions traced by a given use of TRACE.
- Options may also be interspersed with function names, in which case they
- act as local options, only affecting tracing of the immediately preceding
- function name. Local options override global options.
+The NAMEs are not evaluated. Each may be a symbol, denoting an
+individual function, or a string, denoting all functions fbound to
+symbols whose home package is the package with the given name.
