determine if a String contains a String

Mark Volkmann
What's the recommended way to determine if a String contains another  
String?
I found one way.

'*substring*' matches: string

I'm sure I could use a regular expression, but that seems like overkill.
At first I thought I should use include: or contains: from Collection,  
but apparently not.

While we are on the subject, is there an easy way to replace a substring with another one?  I couldn't figure out any other way than to collect: the substrings and then put them back together...

Thanks! It looks like the method name is "includesSubString:". Notice  
the last capital "S". That seems weird. There is another method named  
"includesSubstring:caseSensitive:" where that "s" isn't uppercase.
