JEdit pretty print

[Rolf.Kemper]

Dear ALL,

I start to work with Jedit (4.3).
I have read that there is a class "Software:retty Printer" which is
able to pretty up my document. There is also mentioned that it will
work with Jedit.

I need some help how to make this work with Jedit.

What do I have to do ? (download , install ???)
Is this handled like a plugin? (I have never installed one)

So, some intructions how to get there would be helpfull.

Rolf
