Trimming Blanks from the Ends of a String

Problem

You need to ignore leading or trailing space in a string

Solution

SRFI-13 to the rescue again, in the form of string-trim, string-trim-right, and string-trim-both: 
> (require (lib "13.ss" "srfi"))
> (string-trim "   Some text  ")
"Some text  "
> (string-trim-right "   Some text  ")
"   Some text"
> (string-trim-both "   Some text  ")
"Some text"

Discussion

I added the require so that the example was "standalone" wrt to a stock MzScheme REPL environment.
