I always wanted to write a compiler whose front-end consumes Prolog and back-end emits PostScript, and call it "PrologueToPostscript".

prologue: a separate introductory section of a literary, dramatic, or musical work.

postscript: an additional remark at the end of a letter, after the signature and introduced by ‘PS’.
