+transformation with trampoline technique for Node.js
 
 JavaScript is a nice programming language, but compared to Scheme,
-it lacks the tail call optimization.
-Node.js is often used with Callback Passing Style programming
-without tail call optimization.
+it doesn't handle tail calls properly.
+Node.js is often used with callback functions,
+which tend to be tail calls (but not necessarily recursions).
 
 This module allows to transform native JavaScript code into
-Continuation Passing Style (CPS) code in a best effort manner.
-It utilizes so-called trampoline technique to avoid the stack overflow error.
