How can I see the actual code of the specialized structures

[Fernando Rodriguez]

 Hello: I´m new using MySql++; and I have a question.
 How can I see the actual code of the specialized structures??
 
 In the documentation I found this:
 
 To see the actual code that the macro inserts use sql++pretty. For example:

     sql++pretty < test.cc | less
 
 but I don´t know if "sql++pretty" is a command for c++ or what. I use
 it like a command, but don´t works. Can you help me please?
 
 Thank you........
