Subject: Re: what does *my_array do?

It expands the array into arguments.  For example:

my_array = [ "str1", "str2", "str3" ]
listbox.add(*my_array)

is the same as

listbox.add("str1", "str2", "str3")

Many Ruby APIs make it easier on the developer by automatically  
expanding the array if it's the lone argument, but I guess tk  
doesn't, at least not in this case.
