[plt-scheme] Obtaining a readable ascii file from a .scm containing tests

Hello,

Is there an automatic way of having a readable ascii file from a .scm  
that contains a lot of tests ?
I could do it manually, by defining myself a function assert, and  
then rewrite all the test, but this is boring...

Cheers,
Alexandre
